About Gja1

Summary

Enables connexin binding activity; gap junction channel activity; and protein domain specific binding activity. Involved in several processes, including blood vessel diameter maintenance; negative regulation of cell population proliferation; and reproductive structure development. Located in several cellular components, including endosome; fascia adherens; and gap junction. Part of connexin complex. Used to study Parkinsonism; amnestic disorder; high grade glioma; and myocardial infarction. Biomarker of several diseases, including artery disease (multiple); autoimmune thyroiditis; borna disease; ischemia (multiple); and tongue squamous cell carcinoma. Human ortholog(s) of this gene implicated in several diseases, including autosomal recessive craniometaphyseal dysplasia; congenital heart disease (multiple); erythrokeratodermia variabilis (multiple); oculodentodigital dysplasia; and palmoplantar keratoderma and congenital alopecia 1. Orthologous to human GJA1 (Gap Junction Protein alpha 1). [provided by Alliance of Genome Resources, Apr 2022]
