NCIt definition : Insulin-like growth factor-binding protein 6 (240 aa, 25 kDa) is encoded by the human
IGFBP6 gene. This protein plays a role in insulin-like growth factor binding.;
NCIt note : IGFBP6 contains a thyroglobulin type-I domain, belongs to the IGFBP family, and may
function as an autocrine growth inhibitor. IGFBPs display strong sequence homologies.
IGFBPs contain three distinct domains. N-terminal domain 1 and C-terminal domain 3
contain invariant cysteine residues and are the IGF binding domains. Domain 2 generally
lacks sequence identity among the IGFBPs. Domain 3 is homologous to the thyroglobulin
type I repeat. IGF-I and IGF-II circulate in plasma tightly bound to IGFBPs. IGFs,
IGFRs, and IGFBPs regulate cell proliferation and apoptosis and the primary effect
of IGFBPs appears to be modulation of IGF activity and control of IGF-mediated cell
growth and metabolism. Secreted IGF-binding proteins prolong the half-life of IGFs
(somatomedins) and either inhibit or stimulate the growth promoting effects of IGFs
by altering the interaction of IGFs with cell surface receptors. (from OMIM 146735,
