HEF1 protein (Tagged-His Tag) (ab92252)
This protein was expressed as an N-terminal His-tag fusion protein using Escherichia coli, and purified using Immobilized Metal Ion Affinity Chromatography. In some cases, smaller protein fragments may be present in addition to the intended expression product as a result of premature termination during translation in E. coli and subsequent co-purification via the His-tag. In some cases purified proteins run at a molecular weight different to the theoretically calculated molecular weight. This may be as a result of unequally distributed charges in the amino acid sequence. Alternatively, dimerisation of the expression product can occur under oxygen limitation during expression/cultivation.

Contains 1 SH3 domain.
The SH3 domain interacts with two proline-rich regions of focal adhesion kinase.
modificationsCell cycle-regulated processing produces four isoforms: p115, p105, p65, and p55. Isoform p115 arises from p105 phosphorylation and appears later in the cell cycle. Isoform p55 arises from p105 as a result of cleavage at a caspase cleavage-related site and it appears specifically at mitosis. The p65 isoform is poorly detected.
Focal adhesion kinase 1 phosphorylates the protein at the YDYVHL motif (conserved among all cas proteins). The SRC family kinases (FYN, SRC, LCK and CRK) are recruited to the phosphorylated sites and can phosphorylate other tyrosine residues. Ligation of either integrin beta-1 or B-cell antigen receptor on tonsillar B-cells and B-cell lines promotes tyrosine phosphorylation and both integrin and BCR-mediated tyrosine phosphorylation requires an intact actin network. In fibroblasts transformation with oncogene v-ABL results in an increase in tyrosine phosphorylation. Transiently phosphorylated following CD3 cross-linking and this phosphorylated form binds to CRK and C3G. A mutant lacking the SH3 domain is phosphorylated upon CD3 cross-linking but not upon integrin beta-1 cross-linking. Tyrosine phosphorylation occurs upon stimulation of the G-protein coupled C1a calcitonin receptor in rabbit. Calcitonin-stimulated tyrosine phosphorylation is mediated by calcium- and protein kinase C-dependent mechanisms and requires the integrity of the actin cytoskeleton.
