Insulin is a relatively simple protein consisting of 51 amino acids arranged as two polypeptide chains, an α- chain and β-chain, connected by disulfide bonds; the latter are necessary to maintain tertiary structure and biological activity. Although the amino acid sequence and composition of animal...

We will use the amino acid numbering of human IGF1R to describe our subsequent structural and functional analyses, as most previous studies reported in the literature focus on human IGF1R. Table 1 Cryo-EM data collection, refinement, and validation statistics Full size table Fig. 1 Overall ...

(IRS) proteins. When these proteins become phosphorylated they in turn phosphorylate a number of intracellular kinases and phosphatases. These activatedenzymesthen stimulateglucoseand amino acid uptake, and a number of rate-limiting reactions in various metabolic pathways. These actions determine the net...
Taken together, the data suggest that the 92- and 97-kDa subunits differ in primary amino acid sequence. Thus, two distinct beta subunits may be present in a single IGF-1 receptor in brain. These subunits have in common an epitope recognized by an antibody to the tyrosine kinase domain (...
Ghrelin is a 28 amino acid peptide mainly derived from the oxyntic gland of the stomach. Both acylated (AG) and unacylated (UAG) forms of ghrelin are found in the circulation. Initially, AG was considered as the only bioactive form of ghrelin. However, recent advances indicate that both AG...
Porcine Insulin is a double-chain protein with a molecular mass of 5778, containing 51 amino acids (A-21 and B-30 chains) connected by a disulfide bond. Porcine Insulin has a high degree of similarity to human insulin, differing only in the 30th amino acid. porcine Insulin regulates the ...
(SUMO1, −2 or −3). We found that DRP1 was efficiently sumoylated by SUMO2 and SUMO3 but not SUMO1 in NIT-1 cells (Fig.4c). The lysine residue at the 597th amino acid of DRP1 (LKTSK597AEE) was identified as the major sumoylation site of DRP1 since little sumoylation by ...
