A1BG Protein Overview: Sequence, Structure, Function and Protein Interaction

A1BG Protein Overview

A1BG reagents

Ishioka et al. (1986) determined the complete amino acid sequence of the plasma protein alpha-1B-glycoprotein. The protein contains 474 amino acids and has 5 intrachain disulfide bonds. Sequence homology to immunoglobulins was recognized. Alpha-1B-glycoprotein is present in normal adult plasma at an average concentration of 22 mg/dl.
