CCDC43 is a human protein whose function is not presently understood. Coding sequence diversity are 2 isoforms produced by alternative splicing. Isoform 1 has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. Recombinant human CCDC43 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
