RET proto-oncogene; also known as RET; is a cell-surface molecule that transduce signals for cell growth and differentiation. It contains 1 cadherin domain and 1 protein kinase domain. RET proto-oncogene belongs to the protein kinase superfamily; tyr protein kinase family. RET proto-oncogene is involved in numerous cellular mechanisms including cell proliferation; neuronal navigation; cell migration; and cell differentiation upon binding with glial cell derived neurotrophic factor family ligands. It phosphorylates PTK2/FAK1 and regulates both cell death/survival balance and positional information. RET is required for the molecular mechanisms orchestration during intestine organogenesis; involved in the development of enteric nervous system and renal organogenesis during embryonic life; promotes the formation of Peyer's patch-like structures; modulates cell adhesion via its cleavage; involved in the development of the neural crest. RET proto-oncogene is active in the absence of ligand; triggering apoptosis. RET acts as a dependence receptor; in the presence of the ligand GDNF in somatotrophs (within pituitary); promotes survival and down regulates growth hormone (GH) production; but triggers apoptosis in absence of GDNF. It also regulates nociceptor survival and size; triggers the differentiation of rapidly adapting (RA) mechanoreceptors; mediated several diseases such as neuroendocrine cancers. Defects in RET may cause colorectal cancer; hirschsprung disease type 1; medullary thyroid carcinoma; multiple neoplasia type 2B; susceptibility to pheochromocytoma; multiple neoplasia type 2A; thyroid papillary carcinoma and congenital central hypoventilation syndrome.Immune Checkpoint Immunotherapy Cancer Immunotherapy Targeted Therapy
The specific activity was determined to be 17 nmol/min/mg using synthetic TRK-C-derived Peptide (R11-VYSTDYYRLFNPS) as substrate.
Endotoxin:
<1.0 EU per µg as determined by the LAL method.
Protein Construction:
A DNA sequence encoding the cytoplasmic domain of human RET (P07949-1) (His 658-Ser 1114) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
