Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: F-actin capping protein, alpha subunit

The F-actin capping protein is a heterodimer composed of two unrelated alpha and beta subunits. Neither of the subunits shows sequence similarity to other filament-capping proteins PMID:2341404.

This superfamily represents the alpha subunit of the F-actin capping protein (CAPZA), a protein of about 280 amino acid residues whose sequence is well conserved in eukaryotic species PMID:1711931. In Drosophila mutations in the alpha and beta subunits cause actin accumulation and subsequent retinal degeneration PMID:16143599. In humans CAPZA is part of the WASH complex that controls the fission of endosomes PMID:19922875.
