C4BPA - complement component 4 binding protein alpha Gene
Also Known as PRP; C4BP
Species: Homo sapiens
About C4BPA
This gene has 3 transcripts (splice variants), 146 orthologues and 39 paralogues. Biased expression in liver (RPKM 372.5) and lung (RPKM 75.1).
Summary
This gene encodes a member of a superfamily of proteins composed predominantly of tandemly arrayed short consensus repeats of approximately 60 Amino acids. Along with a single, unique beta-chain, seven identical alpha-chains encoded by this gene assemble into the predominant isoform of C4b-binding protein, a multimeric protein that controls activation of the complement cascade through the classical pathway. The genes encoding both alpha and beta chains are located adjacent to each Other on human chromosome 1 in the regulator of complement activation gene cluster. Two pseudogenes of this gene are also found in the cluster. [provided by RefSeq, Jul 2008]
