Noelin-2 (OLFM2)

Involved in transforming growth factor beta (TGF-beta)- induced smooth muscle differentiation. TGF-beta induces expression and translocation of OLFM2 into the nucleus where it binds to SRF, inducing its dissociation in 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.
