Summaries for APOA2 Gene

Entrez Gene Summary for APOA2 Gene

  • This gene encodes apolipoprotein (apo-) A-II, which is the second most abundant protein of the high density lipoprotein particles. The protein is found in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D. Defects in this gene may result in apolipoprotein A-II deficiency or hypercholesterolemia. [provided by RefSeq, Jul 2008]

GeneCards Summary for APOA2 Gene

APOA2 (Apolipoprotein A-II) is a Protein Coding gene. Diseases associated with APOA2 include apolipoprotein a-ii deficiency and familial renal amyloidosis due to apolipoprotein aii variant. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include protein homodimerization activity and phospholipid binding.
