α2β1 Integrin Ligand Peptide TFA interacts with the integrin receptor on the cell membrane and enters the cell to mediate extracellular signaling.It is a potential antagonist of the collagen receptor.

Insulin Receptor (1142 - 1153), pTyr1150, Biotinylated

This is a hypoxia-inducible factor-1 (HIF-1 a) 19-mer fragment. HIF-1 functions as master regulator of response to oxygen homeostasis. Hypoxia-induced gene expression is initiated when HIF-1 subunit is stabilized in response to a lack of oxygen. This part of HIF-1 binds to the von Hippel-Lindau factor (VHL) an E3 ubiquitin ligase, and the proline 564 is absolutely critical to the binding process.
