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 and Keratoconus.

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 Asn 92, Asn 133, Asn 167, Asn 177, Asn 191, Asn 267, Asn 322, and Asn 331
