Lipid phosphate phosphohydrolase 3 (LPP3), also known as phospholipid phosphatase 3 (PLPP3) and phosphatidic acid phosphatase type 2B (PAP-2b or PPAP2B), is an enzyme that in humans is encoded by the PPAP2B gene on chromosome 1. [5] [6] [7] It is ubiquitously expressed in many tissues and cell types. [8]
Acid phosphatase (EC 3.1.3.2, systematic name phosphate-monoester phosphohydrolase (acid optimum)) is an enzyme that frees attached phosphoryl groups from other molecules during digestion. It can be further classified as a phosphomonoesterase .
The coding sequence for this form of alkaline phosphatase is unique in that the 3' untranslated region contains multiple copies of an Alu family repeat. In addition, this gene is polymorphic and three common alleles (type 1, type 2, and type 3) for this form of alkaline phosphatase have been well-characterized.
Clinical significance [ edit ] Clinically, increased expression of ACP1 is a biomarker for poor prognosis in prostate cancer has been linked to worse clinical behaviour of prostate cancer, possibly outperforming the widely used Gleason grading system with respect to this important parameter. [ 6 ]
PTEN acts as a tumor suppressor gene through the action of its phosphatase protein product. This phosphatase is involved in the regulation of the cell cycle, preventing cells from growing and dividing too rapidly. [8] It is a target of many anticancer drugs. The protein encoded by this gene is a phosphatidylinositol-3,4,5-trisphosphate 3 ...
The severity of symptoms ranges from premature loss of deciduous teeth with no bone abnormalities to stillbirth [18] depending upon which amino acid [19] [20] is changed in the ALPL gene. Mutations in the ALPL gene lead to varying low activity of the enzyme tissue-nonspecific alkaline phosphatase (TNSALP or TNAP) resulting in hypophosphatasia ...
The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found in the periplasmic ...
The clinical significance of the biochemical consequences that result from the genetic abnormalities in patients with CPT II Deficiency is a contested issue. Rufer et al. support the theory that there is an association between level of enzyme activity and clinical presentation. [13]
