Entrez Gene Summary for ACP4 Gene

  • Acid phosphatases are enzymes capable of hydrolyzing orthophosphoric acid esters in an acid medium. This gene is up-regulated by androgens and is down-regulated by estrogens in the prostate cancer cell line. This gene exhibits a lower level of expression in testicular cancer tissues than in normal tissues. The protein encoded by this gene has structural similarity to prostatic and lysosomal acid phosphatases. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

GeneCards Summary for ACP4 Gene

ACP4 (Acid Phosphatase 4) is a Protein Coding gene. Diseases associated with ACP4 include Amelogenesis Imperfecta, Type Ij and Hypoplastic Amelogenesis Imperfecta. An important paralog of this gene is ACP2.

UniProtKB/Swiss-Prot for ACP4 Gene

  • May dephosphorylate receptor tyrosine-protein kinase ERBB4 and inhibits its ligand-induced proteolytic cleavage (PubMed:15219672). May play a role in odontogenesis (PubMed:27843125).

  • Amelogenesis imperfecta 1J (AI1J) [MIM:617297]: A form of amelogenesis imperfecta, a disorder characterized by defective enamel formation. The enamel may be hypoplastic, hypomineralized or both, and affected teeth may be discoloured, sensitive or prone to disintegration. AI1J is an autosomal recessive form characterized by hypoplastic enamel, enamel discolorization ranging from yellow to black, and normal dentin. {ECO:0000269 PubMed:27843125}. Note=The disease is caused by mutations affecting the gene represented in this entry.
