BMP and activin membrane bound inhibitor(BAMBI) Homo sapiens This gene encodes a transmembrane glycoprotein related to the type I receptors of the transforming growth factor-beta (TGF-beta) family, whose members play important roles in signal transduction in many developmental and pathological processes. The encoded protein however is a pseudoreceptor, lacking an intracellular serine/threonine kinase domain required for signaling. Similar proteins in frog, mouse and zebrafish function as negative regulators of TGF-beta, which has led to the suggestion that the encoded protein may function to limit the signaling range of the TGF-beta family during early embryogenesis.

Function:
developmental stage:Expression in poorly metastatic human melanoma cell lines; no expression in highly metastatic human melanoma cell lines.,Function:Negatively regulates TGF-beta signaling.,similarity:Belongs to the BAMBI family.,tissue specificity:High expression in kidney medulla, placenta and spleen; low in kidney cortex, liver, prostate and gut. Not expressed in normal skin, expression is high in melanocytes and in 3 out of 11 melanoma metastases tested.,
