Single nucleotide polymorphism (SNP) of complement component 2 (C2) has been found to be significantly associated with hepatocellular carcinoma (HCC). Significantly lower C2 expression was found at HCC compared to healthy controls, and C2 was associated with TNM stages. Higher C2 expression was significantly associated with better prognosis, and multivariate analysis showed that C2 was also an independent factor for the prognosis of HCC.

molecular weight

The protein has a predicted MW of 82.2 kDa (Pro form). Due to glycosylation, the protein migrates to 83-90 kDa (Pro form) based on Tris-Bis PAGE result.
