Phostensin

PFAM accession number:	PF13914
Interpro abstract (IPR025907):	Phostensin has been identified as a PP1 regulatory protein, binding PP1 at the KISF motif found in this domain. This domain also appears to carry an incomplete SH3-binding domain PxRxP further upstream. It is likely that phostensin targets PP1 to the F-actin cytoskeleton [ (PUBMED:17374523) ]. Phostensin binds to actin and decreases the elongation and depolymerisation rates of actin filament pointed ends [ (PUBMED:19622346) ]. This domain is also found in the taperin, which is a PP1 binding protein that is ancestrally related to phostensin. Taperin has a role in sound perception [ (PUBMED:20170899) ].
GO function:	phosphatase binding (GO:0019902)
