背景介绍
To reach fertilization competence, spermatozoa undergo a series of morphological and molecular maturational processes, termed capacitation, involving protein tyrosine phosphorylation and increased intracellular calcium. The protein encoded by this gene localizes to the principal piece of the sperm flagellum in association with the fibrous sheath and exhibits calcium-binding when phosphorylated during capacitation. A pseudogene on chromosome 3 has been identified for this gene. Alternatively spliced transcript variants encoding distinct protein isoforms have been found for this gene.

组织表达
Expressed in elongating spermatids and spermatozoa (at protein level). Isoform 1 is expressed in testis. Isoform 3 and isoform 5 are also expressed in brain, pancreas and numerous brain tumors.

功能
function:May function as a regulator of both motility- and head-associated functions such as capacitation and the acrosome reaction. Isoform 1 binds calcium in vitro. Isoform 2 and isoform 6 probably bind calcium. Isoform 3 and isoform 5 do not bind calcium in vitro. Isoform 4 probably does not bind calcium.,PTM:Isoform 1 is phosphorylated on tyrosine residues during in vitro capacitation. Isoform 3 and isoform 5 are phosphorylated by GSK3B in vitro. Dephosphorylation affects its ability to bind calcium.,similarity:Contains 1 RIIa domain.,subcellular location:According to PubMed:15752768, isoform 1, isoform 3 and isoform 5 are both nuclear and cytoplasmic.,subcellular location:According to Ref.4, isoform 1, isoform 3 and isoform 5 are both nuclear and cytoplasmic.,subcellular location:Localized to fibrous sheath including the surface of the longitudinal columns and ribs of the principal piece of sperm flagella.,subunit:Interacts with FSCB (By similarity). Isoform 3 self-associates. Isoform 3 and isoform 5 interact with GSK3B. Isoform 1 does not interact with GSK3B.,tissue specificity:Expressed in elongating spermatids and spermatozoa (at protein level). Isoform 1 is expressed in testis. Isoform 3 and isoform 5 are also expressed in brain, pancreas and numerous brain tumors.,
纯化
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.
