C1QA Protein Overview: Sequence, Structure, Function and Protein Interaction

C1QA Protein Overview

C1QA reagents

The first component of complement is a calcium-dependent complex of the 3 subcomponents C1q, C1r (613785), and C1s (120580). Subcomponent C1q binds to immunoglobulin complexes with resulting serial activation of C1r (enzyme), C1s (proenzyme), and the other 8 components of complement. C1q is composed of 3 different species of chains, called A, B (C1QB; 120570), and C (C1QC; 120575).For a review of the complement system and its components, see Degn et al. (2011).
