該基因編碼的蛋白有一個N-末端，與枯草芽孢桿菌的多拷貝相關絲狀（maf）蛋白和大腸桿菌的orfE相似，而C-末端與N-乙酰5-羥色胺O-甲基轉移酶相似該基因位于X染色體和Y染色體的假常染色體區1（PAR1）。已經發現了三個編碼不同亞型的轉錄變體[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]
