Clan: SICA_like (CL0474)

Summary

SICA alpha/beta like extracellular domains Add an annotation

The SICA (schizont-infected cell agglutination) proteins of P. knowlesi, one of the variant antigen gene families, are associated with parasitic virulence. These proteins are comprised of three domains (alpha, beta and C-terminal). The two extracelullar domains, termed SICA alpha and beta, occur with varying copy number. The alpha domain, although it appears to be related to the beta domain, contains few cysteine residues and is found between 1 and 2 times, compared with the beta domain that occurs between 1 and 10 times (when present) [1].

This clan contains 2 families and the total number of domains in the clan is 575. The clan was built by RD Finn.
