STRUCTURE OF MELANOMA INHIBITORY ACTIVITY PROTEIN: A MEMBER OF A NEW FAMILY OF SECRETED PROTEINS
Contents |
Overview
Melanoma inhibitory activity (MIA) is a 12-kDa protein that is secreted from both chondrocytes and malignant melanoma cells. MIA has been reported to have effects on cell growth and adhesion, and it may play a role in melanoma metastasis and cartilage development. We report the 1.4-A crystal structure of human MIA, which consists of an Src homology 3 (SH3)-like domain with N- and C-terminal extensions of about 20 aa. each. The N- and C-terminal extensions add additional structural elements to the SH3 domain, forming a previously undescribed fold. MIA is a representative of a recently identified family of proteins and is the first structure of a secreted protein with an SH3 subdomain. The structure also suggests a likely protein interaction site and suggests that, unlike conventional SH3 domains, MIA does not recognize polyproline helices.
Disease
Known disease associated with this structure: Myocardial infarction, susceptibility to OMIM:[611082]
