Entrez Gene Summary for DSP Gene

  • Desmosomes are intercellular junctions that tightly link adjacent cells. Desmoplakin is an obligate component of functional desmosomes that anchors intermediate filaments to desmosomal plaques. The N-terminus of desmoplakin is required for localization to the desmosome and interacts with the N-terminal region of plakophilin 1 and plakoglobin. The C-terminus of desmoplakin binds with intermediate filaments. In the mid-region of desmoplakin, a coiled-coiled rod domain is responsible for homodimerization. Mutations in this gene are the cause of several cardiomyopathies and keratodermas as well as the autoimmune disease paraneoplastic pemphigus. [provided by RefSeq, Jul 2008]

GeneCards Summary for DSP Gene

DSP (Desmoplakin) is a Protein Coding gene. Diseases associated with DSP include keratosis palmoplantaris striata ii and cardiomyopathy, dilated, with woolly hair and keratoderma. Among its related pathways are ERK Signaling and Adhesion. GO annotations related to this gene include structural molecule activity and protein binding, bridging. An important paralog of this gene is DST.
