Description
Human Insulin R / CD220 (28-944) Protein, His Tag (MALS & SPR verified) | INR-H52Ha-100ug| Gentaur Distribution US, UK & Europe
Insulin receptor (INSR) is also known as CD antigen CD220, which can be cleaved into the following 2 chains: Insulin receptor subunit alpha and Insulin receptor subunit beta. INSR is a tetramer of 2 alpha and 2 beta chains linked by disulfide bonds. The alpha chains carry the insulin-binding regions, while the beta chains carry the kinase domain. Forms a hybrid receptor with IGF1R, the hybrid is a tetramer consisting of 1 alpha chain and 1 beta chain of INSR and 1 alpha chain and 1 beta chain of IGF1R. In addition to binding insulin, the insulin receptor can bind insulin-like growth factors (IGFI and IGFII). Isoform Short of INSR has a higher affinity for IGFII binding. When present in a hybrid receptor with IGF1R, INSR binds IGF1.
Source: Human Insulin R (28-944), His Tag (INR-H52Ha) is expressed from human 293 cells (HEK293). It contains AA His 28 - Lys 944 (Accession # P06213-2).
