RPB1 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template. At the start of transcription, a single-stranded DNA template strand of the promoter is positioned within the central active site cleft of Pol II. A bridging helix emanates from RPB1 and crosses the cleft near the catalytic site and is thought to promote translocation of Pol II by acting as a ratchet that moves the RNA-DNA hybrid through the active site by switching from straight to bent conformations at each step of nucleotide addition. During transcription elongation, Pol II moves on the template as the transcript elongates. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing. Involved in the transcription of several genes including those involved in embryogenesis.
Following transcription stress, the elongating form of RNA polymerase II (RNA pol IIo) is polyubiquitinated via 'Lys-63'-linkages on Lys-1260 at DNA damage sites without leading to degradation: ubiquitination promotes RNA pol IIo backtracking to allow access by the transcription-coupled nucleotide excision repair (TC-NER) machinery. Subsequent DEF1-dependent polyubiquitination by the elongin complex via 'Lys-48'-linkages may lead to proteasome-mediated degradation; presumably at stalled RNA pol II where TC-NER has failed, to halt global transcription and enable 'last resort' DNA repair pathways.
The C-terminal domain (CTD) serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing.
The binding of ribonucleoside triphosphate to the RNA polymerase II transcribing complex probably involves a two-step mechanism. The initial binding seems to occur at the entry (E) site and involves a magnesium ion temporarily coordinated by three conserved aspartate residues of the two largest RNA Pol II subunits. The ribonucleoside triphosphate is transferred by a rotation to the nucleotide addition (A) site for pairing with the template DNA. The catalytic A site involves three conserved aspartate residues of the RNA Pol II largest subunit which permanently coordinate a second magnesium ion.
The tandem 7 residues repeats in the C-terminal domain (CTD) can be highly phosphorylated. The phosphorylation activates Pol II. Phosphorylation occurs mainly at residues 'Ser-2' and 'Ser-5' of the heptapeptide repeat and starts at the 3- to 4-cell embryonic stage. This phosphorylation also occurs in the early stages of oocyte development and is not detected in oocytes arrested at the meiotic diakinesis stage. In the somatic lineage, phosphorylation at 'Ser-2' is mediated by cdk-12 downstream of cdk-9 whereas in the germline lineage cdk-12 phosphorylates 'Ser-2' independently of cdk-9. Phosphorylation is likely mediated by cdk-7. May be dephosphorylated by fcp-1 in diakinetic oocytes and in 1-cell and 2-cell embryos. Dephosphorylated at 'Ser-5' of the heptapeptide repeat by ssup-72. The phosphorylation state is believed to result from the balanced action of site-specific CTD kinases and phosphatase, and a 'CTD code' that specifies the position of Pol II within the transcription cycle has been proposed.

Belongs to the V-ATPase proteolipid subunit family.
Proton-conducting pore forming of the V0 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons. V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments and in some cell types, is targeted to the plasma membrane, where it is responsible for acidifying the extracellular environment (By similarity). Involved in necrotic cell death. Required along with other vacuolar ATPase components for the removal of protein aggregates which form in immature oocytes in the distal gonad. This removal occurs as the oocytes mature and move to the proximal gonad, is triggered by the introduction of sperm through mating and occurs before fertilization. The introduction of sperm triggers V-ATPase accumulation in proximal oocytes and induces lysosomal acidification which leads to engulfing of protein aggregates by lysosomes and subsequent clearance of the aggregates. Lysosomal acidification also leads to changes in mitochondrial morphology and function. Mitochondria in distal immature oocytes are fragmented, produce high levels of reactive oxygen species (ROS) and have high membrane potential, indicative of metabolic inactivity. In contrast, mitochondria in proximal mature oocytes are tubular with lower ROS levels and membrane potential, indicative of an active metabolic state required for aggregate mobilization before clearance (By similarity).

ATP binding drives the homodimer towards the closed dimer state, facilitating recognition of newly synthesized TA membrane proteins. ATP hydrolysis is required for insertion. Subsequently, the homodimer reverts towards the open dimer state, lowering its affinity for the membrane-bound receptor, and returning it to the cytosol to initiate a new round of targeting.

Catalytic subunit of the V1 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons (By similarity). V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments and in some cell types, is targeted to the plasma membrane, where it is responsible for acidifying the extracellular environment (By similarity). Required along with other vacuolar ATPase components for the removal of protein aggregates which form in immature oocytes in the distal gonad.

Heterodimer of a large membrane-associated beta subunit and a small pyruvoyl-containing alpha subunit.
Is synthesized initially as an inactive proenzyme. Formation of the active enzyme involves a self-maturation process in which the active site pyruvoyl group is generated from an internal serine residue via an autocatalytic post-translational modification. Two non-identical subunits are generated from the proenzyme in this reaction, and the pyruvate is formed at the N-terminus of the alpha chain, which is derived from the carboxyl end of the proenzyme. The autoendoproteolytic cleavage occurs by a canonical serine protease mechanism, in which the side chain hydroxyl group of the serine supplies its oxygen atom to form the C-terminus of the beta chain, while the remainder of the serine residue undergoes an oxidative deamination to produce ammonia and the pyruvoyl prosthetic group on the alpha chain. During this reaction, the Ser that is part of the protease active site of the proenzyme becomes the pyruvoyl prosthetic group, which constitutes an essential element of the active site of the mature decarboxylase.

Belongs to the acetyltransferase ATAT1 family.
Specifically acetylates 'Lys-40' in alpha-tubulin/mec-12 on the lumenal side of microtubules. Promotes microtubule destabilization and accelerates microtubule dynamics; this activity may be independent of acetylation activity. Acetylates alpha-tubulin with a slow enzymatic rate, due to a catalytic site that is not optimized for acetyl transfer. Enters the microtubule through each end and diffuses quickly throughout the lumen of microtubules. Acetylates only long/old microtubules because of its slow acetylation rate since it does not have time to act on dynamically unstable microtubules before the enzyme is released.
