Protein Structure

UniProt Annotation

Function

Anchors cAMP-dependent protein kinase (PKA) and acts as an adapter protein to selectively couple G alpha-13 and Rho. Augments gene activation by the estrogen receptor in an element- specific and ligand-dependent manner. Activates estrogen receptor beta by a p38 MAPK-dependent pathway. Stimulates exchange activity on Rho proteins in vitro, but not on CDC42, Ras or Rac and may bind calcium ions. {ECO:0000269PubMed:11546812, ECO:0000269PubMed:11579095, ECO:0000269PubMed:9627117, ECO:0000269PubMed:9891067}.

Disease Associations

Tissue Specificity

Expressed as a 5.3 kb transcript in hematopoietic cells, skeletal muscle, lung, heart, estrogen- responsive reproductive tissues, including breast ductal epithelium. Also found in testis and breast cancer cell lines. Predominantly expressed as a 10 kb transcript in the heart and at lower levels in the lung, placenta, kidney, pancreas, skeletal muscle and liver. Transcripts of between 6-9 kb are also expressed in myeloid and lymphoid lineages, a variety of epithelial tissues, and in skeletal muscle. {ECO:0000269PubMed:11546812, ECO:0000269PubMed:9627117, ECO:0000269PubMed:9891067}.
