The development of genome technology has opened new possibilities for comparative primate genomics. Non-human primates share approximately 98% genome similarity and provides vital information into the genetic similarities and variances among species utilized as disease models. DNA study links unique genetic variations to common facial attributes such as nose and eyes. This is because of higher adaptation and improved cognitive skills over these sensual areas. Non-protein coding sequences represent approximately 85% of the human DNA under evolutionary restrictions, and the primary part of this is the cis regulatory regions. In this study, a total of 103 tissue specific human enhancers were finalized with help of VISTA Enhancer Browser that showed distinctive expression in the facial tissues and their orthologs were collected. A total of 43 out of 190 transcription factors from TRANSFAC were seen as binding in both Human and Non-Human primate enhancers. It was observed that factor binding sites of 7 of the 43 transcription factors were exclusively gained in the human eye and nose enhancers (Oct, Pax, Sox, MyoD, Foxd3, cRel and Gata). Furthermore, we performed molecular docking through PyMol; DNA & Protein (pdb) structures were modelled by SCFBio & SWISSMODEL respectively to observe interactions of the transcription factors, either by placing the contact surface of the protein exclusively to identify the DNA, to enable a representation to gain information about identification and genetic expression.
