This presumed domain is functionally uncharacterised. This domain is found in eukaryotes. This domain is typically between 439 to 459 amino acids in length. This domain is found associated with <db_xref db="PFAM" dbkey="PF00271"/>, <db_xref db="PFAM" dbkey="PF02985"/>, and <db_xref db="PFAM" dbkey="PF00176"/>. This domain has two completely conserved residues (P and K) that may be functionally important.
