General annotation (Comments)
| 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. |
| Subunit structure | Interacts with FSCB By similarity. Isoform 3 self-associates. Isoform 3 and isoform 5 interact with GSK3B. Isoform 1 does not interact with GSK3B. |
| Subcellular location | Cytoplasm › cytoskeleton. Cell projection › cilium › flagellum. Note: Localized to fibrous sheath including the surface of the longitudinal columns and ribs of the principal piece of sperm flagella. Ref.1 Ref.6 Ref.7 Isoform 1: Nucleus. Cytoplasm. Cell projection › cilium › flagellum. Note: According to Ref.6, isoform 1, isoform 3 and isoform 5 are both nuclear and cytoplasmic. Ref.1 Ref.6 Ref.7 Isoform 3: Nucleus. Cytoplasm. Cell projection › cilium › flagellum. Note: According to Ref.6, isoform 1, isoform 3 and isoform 5 are both nuclear and cytoplasmic. Ref.1 Ref.6 Ref.7 Isoform 5: Nucleus. Cytoplasm. Cell projection › cilium › flagellum. Note: According to Ref.6, isoform 1, isoform 3 and isoform 5 are both nuclear and cytoplasmic. Ref.1 Ref.6 Ref.7 |
| 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. Ref.1 Ref.6 Ref.7 |
| Post-translational modification | 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. Ref.1 Ref.6 Ref.5 |
| Sequence similarities | Contains 1 RIIa domain. |
