IGFBP3(redirected from acid stable subunit of the 140 K IGF complex)
IGFBP3A gene on chromosome 7p13-p12 that encodes a member of the insulin-like growth factor binding protein (IGFBP) family that binds insulin-like growth factors I and II and circulates in the plasma. IGFBP3 binding prolongs the half-life of the IGFs and alters their interaction with cell surface receptors.
