OSTM1

Osteopetrosis-associated transmembrane protein 1 is a protein that in humans is encoded by the OSTM1 gene.[5][6][7] It is required for osteoclast and melanocyte maturation and function.[5]

Function

This gene encodes a protein that may be involved in the degradation of G proteins via the ubiquitin-dependent proteasome pathway. The encoded protein binds to members of subfamily A of the regulator of the G-protein signaling (RGS) family through an N-terminal leucine-rich region. This protein also has a central RING finger-like domain and E3 ubiquitin ligase activity. This protein is highly conserved from flies to humans. Defects in this gene may cause the autosomal recessive, infantile malignant form of osteopetrosis.[7] This is also known as autosomal recessive Albers-Schonberg disease.[5][8]

The OSTM1 gene is regulated by the Microphthalmia-associated transcription factor.[9][10]

Interactions

OSTM1 has been shown to interact with RGS19.[11]
