Protein attributes

Sequence length	621 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Unknown. The presence of the putative catalytic domain of S-adenosyl-L-methionine binding argues for a methyltransferase activity.
Tissue specificity	Widely expressed. In adult, highly expressed in pancreas, placenta, fibroblast, thymus, prostate, testis, ovary and colon. Expressed at lower levels in spleen, small intestine and leukocytes. In fetus, expressed at high levels in the lung and kidney and at lower level in brain and liver.
Miscellaneous	The gene encoding for this protein is located in the pseudoautosomal region 1 (PAR1) of X and Y chromosomes. It represents a unique fusion product of 2 different genes of different evolutionary origin and function. The N-terminus is homologous to the bacterial maf/orfE genes and the C-terminus is homologous to ASMT. Exon duplication, exon shuffling and gene fusion seem to be common characteristics of the PAR1 region.
Sequence similarities	In the N-terminal section; belongs to the maf family.
Sequence caution	The sequence CAA75675.1 differs from that shown. Reason: Frameshift at position 616. The sequence CAA75676.1 differs from that shown. Reason: Frameshift at position 616.
