Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of a two-stranded helix. The binding of profilin to monomeric G-actin cause the sequestration of actin into profilactin complexes, and prevents the polymerization.
Belongs to the diacylglycerol acyltransferase family.
Belongs to the 11S seed storage protein (globulins) family.
Hexamer; each subunit is composed of an acidic and a basic chain derived from a single precursor and linked by a disulfide bond.
Belongs to the 2S seed storage albumins family.
Belongs to the MIP/aquaporin (TC 1.A.8) family.
Belongs to the aromatic acid exporter (TC 2.A.85) family.
Dimer of alpha and beta chains. A typical microtubule is a hollow water-filled tube with an outer diameter of 25 nm and an inner diameter of 15 nM. Alpha-beta heterodimers associate head-to-tail to form protofilaments running lengthwise along the microtubule wall with the beta-tubulin subunit facing the microtubule plus end conferring a structural polarity. Microtubules usually have 13 protofilaments but different protofilament numbers can be found in some organisms and specialized cells.
Tubulin is the major constituent of microtubules, a cylinder consisting of laterally associated linear protofilaments composed of alpha- and beta-tubulin heterodimers. Microtubules grow by the addition of GTP-tubulin dimers to the microtubule end, where a stabilizing cap forms. Below the cap, tubulin dimers are in GDP-bound state, owing to GTPase activity of alpha-tubulin.
