Acts as a transcriptional coactivator of estrogen and progesterone receptors (ESR1 and PGR) upon hormone activation . In presence of estrogen, binds to ESR1-responsive promoters . Required for YAP1 coactivation function on PGR activity . Synergizes with WBP2 in enhancing PGR activity . Modulates expression of post-synaptic scaffolding proteins via regulation of ESR1, ESR2 and PGR (By similarity).
Subcellular locations: Cytoplasm, Nucleus
Translocates from cytoplasm to nucleus when phosphorylated.
Ubiquitous.
