This entry represents the SH3 domain found in Desmoplakin and related proteins [PMID: 21536047].

Desmoplakin (DP) is an integral part of desmosomes, where it links desmosomal cadherins to the intermediate filaments. The N-terminal region of DP contains a plakin domain common to members of the plakin family. Plakin domains contain multiple copies of spectrin repeats (SRs). Spectrin repeats (SRs) consist of three alpha-helices (A, B, and C) that form an antiparallel triple-helical bundle [PMID: 21536047].
