Cytosolic Insulin-Binding Proteins Of Mouse Liver Cells
Abstract:It has been recently shown that insulin retains its biological activity after receptor-directed internalization and it may affect the cell metabolism by interaction with cytosolic insulin-binding proteins (CIBPs). Using affinity chromatography combined with SDS-PAGE and MALDI-TOF mass-spectrometry we have identified 7 proteins from mouse liver cells that specifically bind to the insulin, including adenylate kinase 2 (25.6 kD), kinesin superfamily protein 20B (26.0 kD), hepatic arginase 1 (34.8 kD), fructosebisphosphate aldolase B (39.5 kD), 4-hydroxyphenylpyruvate dioxygenase (45.1 kD), betainehomocysteine methyl-transferase (45.0 kD) and KRIT1 (83.4 kD).

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
