Anti-sp100 antibodies are found in association with primary biliary cirrhosis.[1] The autoimmune target of anti-sp100 is the sp100 nuclear antigen which was identified by its association with primary biliary cirrhosis. 20-30% of patients suffering from primary biliary cirrhosis sp100 Abs.
Immunodominant regions of sp100
- antigenic region 1 - positions 296-311 - Sequence (I K K E K P F S N S K V E C Q A)
- antigenic region 2 - positions 332-351 - Sequence (E G S T D V D E P L E V F I S A P R S E)
(Bolded areas represent the core epitope)[2]
