Background:Involved in transforming growth factor beta(TGF-beta)-induced smooth muscle differentiation. TGF-beta induces expression and nuclear translocation of OLFM2 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).
