Gene Family: Class II Cys-based phosphatases

A subset of : Protein phosphatases

Class II phosphatases: LMW (low-molecular-weight) phosphatases, or acid phosphatases, act on tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates. The class II PTPs contain only one member, low-molecular-weight phosphotyrosine phosphatase (LMPTP). [Source: Pfam]

Genes contained within the family: 1

Approved Symbol Approved Name Previous Symbols Synonyms Chromosome
ACP1 acid phosphatase 1 HAAP, LMW-PTP, LMWPTP 2p25.3


There is only one member of the Class II Cys-based phosphatase family in human. This is a subset of the much larger phosphatase family.
