Predicted to enable DNA binding activity; estrogen receptor binding activity; and transcription coactivator activity. Predicted to be involved in several processes, including cellular response to estrogen stimulus; positive regulation of macromolecule metabolic process; and response to steroid hormone. Predicted to be located in chromatin and cytoplasm. Predicted to be active in nucleus. Is expressed in epidermis and epidermis stratum basale. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 107. Orthologous to human WBP2 (WW domain binding protein 2).
