Protein functionPlays a role in angiogenesis. Participates in the regulation of cell polarity and directional endothelial cell migration by mediating both the activation and recruitment of CDC42 and the reorganization of the actin cytoskeleton at the cell leading edge. Promotes filipodia formation, By similarity. Functions synergistically with PELP1 as a transcriptional coactivator of estrogen receptor-responsive genes. Stimulates histone acetyltransferase activity. Binds to chromatin. {ECO:0000250|UniProtKB:Q8CCN5, ECO:0000269|PubMed:17505058}.
Subcellular locationNucleus {ECO:0000269|PubMed:16617102, ECO:0000269|PubMed:17505058}. Cytoplasm {ECO:0000269|PubMed:16617102, ECO:0000269|PubMed:17505058, ECO:0000269|PubMed:18030336}. Cytoplasm, cytoskeleton {ECO:0000250|UniProtKB:Q8CCN5}. Note=Localizes in the cytoplasm in stationary cells. Translocates from the cytoplasm to the leading edge in motile cells. Colocalizes with microtubules and intermediate filaments in both stationary and motile cells, By similarity. Associates with chromatin. Recruited to estrogen receptor-induced promoters in a PELP1-dependent manner. {ECO:0000250|UniProtKB:Q8CCN5, ECO:0000269|PubMed:17505058}.
