human ... IGF1R(3480)

General description

There are two kinds of IGF receptors based on their relative affinities for IGF1 versus IGF2. The IGF1 receptor prefers IGF1 over IGF2 and weakly binds insulin. IGF1 receptor is a disulfide-linked heterotetrameric transmembrane protein consisting of two alpha (130 kDa) and two beta (95 kDa) subunits. Both the alpha and beta subunits are encoded within a single receptor precursor cDNA. The IGF1 receptor is therefore similar in structure to the insulin receptor. The proreceptor polypeptide is proteolytically cleaved and disulfide-linked to yield the mature heterotetrameric receptor. The IGF1 receptor is highly expressed in all cell types and tissues and is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival.

Specificity

This antibody recognizes IGF-IR.

Immunogen

Epitope: Unknown
KLH-conjugated linear peptide corresponding to human IGF-IR.

Application

Immunoprecipitation Analysis: A previous lot was used by an independent laboratory in IP. (Soos, M., et al. (1992). Journal of Biological Chemistry. 267(18):12955-12963.)
