Secondary Accession Numbers Not Available
Name Insulin-like growth factor 1 receptor
Description Not Available
Synonyms
  1. CD221 antigen
  2. IGF-I receptor
  3. Insulin-like growth factor 1 receptor alpha chain
  4. Insulin-like growth factor 1 receptor beta chain
  5. Insulin-like growth factor I receptor
Gene Name IGF1R
Protein Type Enzyme
Biological Properties
General Function Involved in transmembrane receptor protein tyrosine kinase activity
Specific Function This receptor binds insulin-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. It has a tyrosine-protein kinase activity, which is necessary for the activation of the IGF1-stimulated downstream signaling cascade. When present in a hybrid receptor with INSR, binds IGF1. PubMed:12138094 shows that hybrid receptors composed of IGF1R and INSR isoform Long are activated with a high affinity by IGF1, with low affinity by IGF2 and not significantly activated by insulin, and that hybrid receptors composed of IGF1R and INSR isoform Short are activated by IGF1, IGF2 and insulin. In contrast, PubMed:16831875 shows that hybrid receptors composed of IGF1R and INSR isoform Long and hybrid receptors composed of IGF1R and INSR isoform Short have similar binding characteristics, both bind IGF1 and have a low affinity for insulin
