该基因编码的蛋白有一个N-末端，与枯草芽孢杆菌的多拷贝相关丝状（maf）蛋白和大肠杆菌的orfE相似，而C-末端与N-乙酰5-羟色胺O-甲基转移酶相似该基因位于X染色体和Y染色体的假常染色体区1（PAR1）。已经发现了三个编码不同亚型的转录变体[由RefSeq提供，2010年3月]
The protein encoded by this gene has an N-terminus that is similar to the multicopy associated filamentation (maf) protein of Bacillus subtilis and to orfE of Escherichia coli, while the C-terminus is similar to N-acetylserotonin O-methyltransferase. This gene is located in the pseudoautosomal region 1 (PAR1) of X and Y chromosomes. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]
