Complement C2 (P06681)

Uniprot ID P06681
Protein Name Complement C2
Gene Name C2
Species Homo sapiens (Human)
Basic Information Experiments (0) Disease (0) Interactions
Signal peptide(a) Y Secretome P(b)
Function Component C2 which is part of the classical pathway of the complement system is cleaved by activated factor C1 into two fragments: C2b and C2a. C2a, a serine protease, then combines with complement factor C4b to generate the C3 or C5 convertase.

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
