Disease Association

Arrhythmogenic right ventricular dysplasia, familial, 10 (ARVD10) : A congenital heart disease characterized by infiltration of adipose and fibrous tissue into the right ventricle and loss of myocardial cells, resulting in ventricular and supraventricular arrhythmias. [The disease is caused by variants affecting the gene represented in this entry] | Cardiomyopathy, dilated, 1BB (CMD1BB) : A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. [Disease susceptibility is associated with variants affecting the gene represented in this entry]

Tissue Specificity

Expressed in undifferentiated pluripotent stem cells, expression decreases during differentiation (at protein level) (PubMed:29910125). Expressed in hematopoietic stem cells and circulating endothelial progenitor cells, expression decreases upon increasing cell lineage commitment (at protein level) (PubMed:27338829). Expressed on common myeloid progenitors, pro-myelocytes, pro-erythrocytes and B-cell linage progenitors (at protein level). Expression in mature cell types in the bone marrow and mature leukocyte populations is absent (PubMed:27338829). Expressed by foreskin fibroblasts, expression peaks during the early stage of differentiation reprogramming (at protein level) (PubMed:29910125). Expressed by endothelial cells in both arterioles and venules in the cervix (at protein level) (PubMed:27338829). Expressed in pancreatic alpha-cells, beta-cells and exocrine tissue (at protein level) (PubMed:36309486). Expressed in cardiomyocytes (at protein level) (PubMed:31845994, PubMed:38375917). Expressed in kidney tubular epithelial cells (PubMed:38395410). Expressed in the esophageal mucosa (PubMed:24220297)

Subunit

(Microbial infection) Interacts (via Cadherin 3 domain) with human adenovirus B3 fiber protein (as a homotrimer) (PubMed:29849084, PubMed:30862836). Interacts with human adenovirus 55 fiber protein; the interaction is required for infection of host cells (PubMed:32581096)
