OLFM2
Function
Involved in transforming growth factor beta (TGF-beta)-induced smooth muscle differentiation. TGF-beta induces expression and translocation of OLFM2 to the nucleus where it binds to SRF, causing its dissociation from the transcriptional repressor HEY2/HERP1 and facilitating binding of SRF to target genes (PubMed:25298399). Plays a role in AMPAR complex organization (By similarity). Is a regulator of vascular smooth-muscle cell (SMC) phenotypic switching, that acts by promoting RUNX2 and inhibiting MYOCD binding to SRF. SMC phenotypic switching is the process through which vascular SMCs undergo transition between a quiescent contractile phenotype and a proliferative synthetic phenotype in response to pathological stimuli. SMC phenotypic plasticity is essential for vascular development and remodeling (By similarity).
Post-translational modifications
N-glycosylated.
Tissue Specificity
Expressed in aortic smooth muscle (at protein level) (PubMed:25298399). In the fetus, expressed in the brain and ocular tissues including lens vesicle and optic cup (PubMed:27844144).
Cellular localization
- Secreted
- Synapse
- Membrane
- Nucleus
- Cytoplasm
- Nuclear localization is induced by TGF-beta.
