General annotation (Comments)
| Function | Could be involved in oogenesis. Involved in the regulation of endosome dynamics. Implicated in a novel signal transduction pathway, in which isoform 3 and CSK are sequentially activated by RHOD to regulate the motility of early endosomes through interactions with the actin cytoskeleton. Ref.2 |
| Subunit structure | |
| Subcellular location | Isoform 3: Cytoplasm › cytosol. Early endosome. Note: Isoform 3 is cytosolic but when coexpressed with RHOD, the 2 proteins colocalize to early endosomes. Ref.2 |
| Tissue specificity | Expressed in testis, ovary, small intestine, prostate, lung, liver, kidney and leukocytes. |
| Developmental stage | Expressed from E16 in ovary and testis and during P6-P16 during differentiation of ovarian follicles. |
| Domain | DRFs are regulated by intramolecular GBD-DAD binding where Rho-GTP activates the DRFs by disrupting the GBD-DAD interaction By similarity. |
| Involvement in disease | Defects in DIAPH2 are the cause of premature ovarian failure type 2A (POF2A) [MIM:300511]. An ovarian disorder defined as the cessation of ovarian function under the age of 40 years. It is characterized by oligomenorrhea or amenorrhea, in the presence of elevated levels of serum gonadotropins and low estradiol. Ref.1 |
| Sequence similarities | Belongs to the formin homology family. Diaphanous subfamily. Contains 1 DAD (diaphanous autoregulatory) domain. Contains 1 FH1 (formin homology 1) domain. Contains 1 FH2 (formin homology 2) domain. Contains 1 GBD/FH3 (Rho GTPase-binding/formin homology 3) domain. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: O60879-1) Also known as: DIA-156; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: O60879-2) Also known as: DIA-12C; DIA2B; The sequence of this isoform differs from the canonical sequence as follows: 1081-1101: DNRRVPLERSRSRHNGAISSK → VVNHPCATRANPRSAT | ||||||
| Isoform 3 (identifier: O60879-3) Also known as: DIA2C; The sequence of this isoform differs from the canonical sequence as follows: 45-55: Missing. 149-149: S → SIVGSKVT |
