pfam01595: DUF21 (this model, PSSM-Id:216595 is obsolete and has been replaced by 426337)
Domain of unknown function DUF21
This transmembrane region has no known function. Many of the sequences in this family are annotated as hemolysins, however this is due to a similarity to Treponema hyodysenteriae hemolysin C that does not contain this domain. This domain is found in the N-terminus of the proteins adjacent to two intracellular CBS domains pfam00571.
