This is the very C-terminal, chaperone, domain of the bacteriophage protein endosialidase. It releases itself, via the serine-lysine dyad at the N-terminus, from the remainder of the end-tail-spike. Cleavage occurs after the threonine which is the final residue of the End-tail-spike family, Pfam:PF12219. The endosialidase protein forms homotrimeric molecules in bacteriophages [1]. The catalytic dyad allows this portion of the molecule to be cleaved from the more N-terminal region such that the latter can fold and bind to polysialic acid in the bacterial outer envelope [1].

This domain corresponds to the Intramolecular Chaperone Auto-processing (ICA) domain of myelin regulatory factor (Myrf) located at its C-terminal and belongs to the Peptidase S74 family. It forms a homo-trimer and carries out the auto-cleavage of Myrf releasing the Myrf N-terminal homo-trimer from the ER membrane. This allows its entry to the nucleus to function as a homo-trimer transcription factor [1,2].	Domain
