File:Transmembrane.pngPrediction of the orientation of the transmembrane domains of FAM40A
The secondary structure of FAM40A is predicted to contain twenty-six alpha helices and two beta sheets.[8] The 5' untranslated region of FAM40A is predicted to contain one stem-loop and the 3' untranslated region is predicted to contain eight stem-loop structures.[9] Two miRNAs are predicted to bind to two of the stem-loop structures present in the 3' UTR region.[10]
Homology
FAM40A has no paralogs. However, it does have orthologs stretching all the way back to yeast. It has been suggested that FAM40A is a homolog to the yeast gene FAR11, which is involved in the recovery from cell cycle arrest.[11][12]
The following table represents a small selection of orthologs found using searches in BLAST[13] and BLAT.[14] This is by no means a comprehensive list, however it does show the vast diversity of species where FAM40A orthologs are found.
FAM40A is predicted to have a promoter region 789 base pairs upstream of the start of transcription.[17] The SOXtranscription factors are predicted to bind to the promoter region of the FAM40A gene, possibly indicating a role in sex determination.[17]
