Recombinant Human IGF1R Protein(His & GST Tag) Online Inquiry

Product Name:Recombinant Human IGF1R Protein(His & GST Tag)
Synonym: IGF1R; insulin like growth factor 1 receptor; IGFR; CD221; IGFIR; JTK13
Gene Introduction: Gene ID: 3480. IGF1R, the full name is insulin like growth factor 1 receptor. This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]
