PFAM accession number:PF09788
Interpro abstract (IPR019178):

Phosphatidylinositol-4,5-bisphosphate 4-phosphatases type I and type II, also known as transmembrane proteins 55B and 55A, are two metazoan enzymes that catalyse the hydrolysis of PtdIns-4,5-P(2) to phosphatidylinositol-5-phosphate (PtdIns-5-P) [ (PUBMED:16365287) ].

GO process:phosphatidylinositol dephosphorylation (GO:0046856)
GO function:phosphatidylinositol-4,5-bisphosphate 4-phosphatase activity (GO:0034597)
