Scramblase

 Scramblase
PFAM accession number:PF03803
Interpro abstract (IPR005552):

Scramblase is palmitoylated and contains a potential protein kinase C phosphorylation site. Scramblase exhibits Ca 2+ -activated phospholipid scrambling activity in vitro. There are also possible SH3 and WW binding motifs. Scramblase is involved in the redistribution of phospholipids after cell activation or injury [ (PUBMED:11487015) ].

GO process:plasma membrane phospholipid scrambling (GO:0017121)
GO function:phospholipid scramblase activity (GO:0017128)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Scramblase
