PAD_M

PAD_M
PFAM accession number:PF08527
Interpro abstract (IPR013733):

Peptidylarginine deiminase (PAD) enzymes catalyze the conversion of protein-bound arginine to citrulline. There are five types of PADs known in humans, PAD1-PAD4 and PAD6 [(PUBMED:14579251)]. This entry represents the central non-catalytic domain of protein-arginine deiminase. This domain has an immunoglobulin-like fold [(PUBMED:16567635)].

GO process:protein citrullination (GO:0018101)
GO component:cytoplasm (GO:0005737)
GO function:protein-arginine deiminase activity (GO:0004668), calcium ion binding (GO:0005509)

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