Plays an important role in bone formation and normal bone mineralization. Promotes the differentiation of myoblasts into osteoblasts . May induce the commitment and differentiation of myoblasts into osteoblasts through an enhancement of BMP2 production and interaction with the BMP-RUNX2 pathway. Up-regulates the expression of ATF4, a transcription factor which plays a central role in osteoblast differentiation. Essential for normal spermatogenesis and late testicular differentiation (By similarity).
Cell membrane ; Single-pass type I membrane protein . Cytoplasm . Endoplasmic reticulum membrane .
Expressed in brain microglia (at protein level). Elevated expression levels seen in the brain of patients with Alzheimer disease. Expressed by osteoblast-like cells in bone tissues and follicular dendritic cells in lymphoid tissues.
