Summaries for EPB42 Gene

Entrez Gene Summary for EPB42 Gene

  • Erythrocyte membrane protein band 4.2 is an ATP-binding protein which may regulate the association of protein 3 with ankyrin. It probably has a role in erythrocyte shape and mechanical property regulation. Mutations in the EPB42 gene are associated with recessive spherocytic elliptocytosis and recessively transmitted hereditary hemolytic anemia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for EPB42 Gene

EPB42 (Erythrocyte Membrane Protein Band 4.2) is a Protein Coding gene. Diseases associated with EPB42 include spherocytosis, hereditary, type 5 and epb42-related spherocytosis. GO annotations related to this gene include structural constituent of cytoskeleton and protein-glutamine gamma-glutamyltransferase activity. An important paralog of this gene is F13A1.
