ICT1 Human

DS-1, DS1, Peptidyl-tRNA hydrolase ICT1 mitochondrial, Digestion substraction 1, Immature colon carcinoma transcript 1 protein, ICT1.

Immature Colon Carcinoma Transcript 1 (ICT1) functions as a codon-independent translation release factor that has lost all stop codon specificity and leads the termination of translation in mitochondrion in case of abortive elongation. The mature colon epithelium has 3 differentiated cell types which arise from a multipotent stem cell. ICT1 is involved in the hydrolysis of peptidyl-tRNAs which have been prematurely terminated and consequently in the recycling of stalled mitochondrial ribosomes. Digression from the normal maturation pathway by neoplastic transformation is assumed to originate in stem cells or their early descendants.

ICT1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 200 amino acids (30-206 a.a) and having a molecular mass of 22.8kDa. ICT1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
