WBP2

The globular WW domain is composed of 38 to 40 semiconserved amino acids shared by proteins of diverse functions including structural, regulatory, and signaling proteins. The domain is involved in mediating protein-protein interactions through the binding of polyproline ligands. This gene encodes a WW domain binding protein, which binds to the WW domain of Yes kinase-associated protein by its PY motifs. The function of this protein has not been determined.

WW domain binding protein 2

Acts as transcriptional coactivator of estrogen and progesterone receptors (ESR1 and PGR) upon hormone activation (PubMed:16772533).
In presence of estrogen, binds to ESR1-responsive promoters (PubMed:16772533).
Required for YAP1 coactivation function on PGR activity (PubMed:16772533).
Synergizes with WBP2 in enhancing PGR activity (PubMed:16772533).
Modulates expression of post-synaptic scaffolding proteins via regulation of ESR1, ESR2 and PGR (By similarity).

Translocates from cytoplasm to nucleus when phosphorylated.

Deafness, autosomal recessive, 107 (DFNB107):
A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.

Phosphorylated in repsonse to EGF as well as estrogen and progesterone hormones (PubMed:21642474).
Tyr-192 and Tyr-231 are phosphorylated by YES and SRC inducing nuclear translocation (PubMed:21642474).
