Summaries for ACP2 Gene

Entrez Gene Summary for ACP2 Gene

  • This gene encodes the beta subunit of lysosomal acid phosphatase (LAP). LAP is chemically and genetically distinct from red cell acid phosphatase. The encoded protein belongs to a family of distinct isoenzymes which hydrolyze orthophosphoric monoesters to alcohol and phosphate. LAP-deficiencies in mice cause multiple defects including bone structure alterations, lysosomal storage defects in the kidneys and central nervous system, and an increased tendency towards seizures. An enzymatically-inactive allele of LAP in mice exhibited a more severe phenotype than the null allele, and defects included cerebellum abnormalities, growth retardation, hair-follicle abnormalities, and an ataxia-like phenotype. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

GeneCards Summary for ACP2 Gene

ACP2 (Acid Phosphatase 2, Lysosomal) is a Protein Coding gene. Diseases associated with ACP2 include lysosomal acid phosphatase deficiency. Among its related pathways are Lysosome and Riboflavin metabolism. GO annotations related to this gene include acid phosphatase activity. An important paralog of this gene is ACPP.

Post-translational modifications for ACP2 Gene

  • N-glycosylated. The intermediates formed during enzymatic deglycosylation suggest that all eight predicted N-glycosylation sites are used.
  • The membrane-bound form is converted to the soluble form by sequential proteolytic processing. First, the C-terminal cytoplasmic tail is removed. Cleavage by a lysosomal protease releases the soluble form in the lysosome lumen.
  • Glycosylation at Asn92, Asn133, Asn167, Asn177, Asn191, Asn267, Asn322, and Asn331
  • Modification sites at PhosphoSitePlus
