The SRY gene encodes the SRY protein. The SRY protein is a transcriptional factor that induces the male phenotype in the embryo. The SRY gene is located on the [https://en.wikipedia.org/wiki/Y_chromosome Y chromosome] in the short arm (p) 11.3 <ref>[http://www.ncbi.nlm.nih.gov/gene/6736 NCBI gene]</ref>. This gene has only one exon that contains the HMG domain (DNA-binding High-Mobility Group box domain). It means that SRY mRNA does not have an alternative splicing, so there is only one isoforme of SRY protein<ref name!"McE"> McElreavey K, Barbaux S, Ion A, Fellous M.
