IGFBP6

A gene on chromosome 12q13 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. IGFBP6 binding prolongs the half-life of the IGFs and alters their interaction with cell surface receptors.

IGFBP-6 is a 30 kDa secreted protein, and unlike other IGFBPs, has a significantly higher affinity (~70-100-fold) for IGF-2 than IGF-1 [15, 16].
During development, IGFBP-6 is expressed abundantly in developing muscle cells and is also required for myogenesis [22].
Phosphorylation and O-glycosylation are also involved in affinity changes of IGFBP-6 and cause inhibition of IGF-II action on target cells [26, 27].
La eficacia de los IGF en el ambito celular esta modulada por las proteinas de union al IGF (IGFBP), proteinas homologas de las cuales se han descrito desde IGFBP-1 hasta IGFBP-6. Las observaciones de Hajjar y otros autores sobre IGFBP se resumen en la tabla 2 (61).
The actions of IGFs are mainly mediated via IGF receptor 1 (IGFR-1) and are modulated by six binding proteins (IGFBPs), designated as IGFBP-1 to IGFBP-6 [35, 36].
So far, five IGFBPs (IGFBP-1, 2, 3, 4, 5) and low-affinity IGFBP-7 are identified in NCBI chicken genome (build 2.1), since no IGFBP-6 gene homologue has been identified for chickens.
They also identified linkages to genes in the RA-signaling pathway (IGFBP-3 and IGFBP-6), but again, not the specific genes used in Figure 2.

The best nontarget predictors included Bdnf, Actc1, c-myc single-strand-binding protein, Igfbp-6, and integrin beta4.
IGFBP-6, a member of the IGF binding protein family, is expressed abundantly in developing muscle cells and is required for myogenesis [13].
Moreover, IGF-2 specific binding protein, IGFBP-6, is expressed during embryonic development in many different tissues including the ossifying bones of the cranium, myoblasts, and the motor neurons of the spinal cord [112].
