BLAST search for whole sequence turns out a high number of similar matches. Top few matches were used to generate a phylogenetic tree.

Both phylogenetic trees from CLUSTALX and PHYLIP both show similar results with PHYLIP being known as the more accurate version for study.

It is not suprising that the closest related to the human is the chimpanzee's gene and orangutan. It has long been known that these are the two closest related animals to humans and so this result is to be expected. The suprising result is for the mouse genes. There are 4 genes all closely related and branching off with 3 being off the same branch with slight differences. All the mouse genes are similar with the top one a confirmed and studied example and subsequent genes all showing very close matches. With the high degree of nucleotide match and studied and identified genes of many species it is arguable that the genes labeled as "predicted" and "hypothetical" are of that function. The mouse gene seems to be the genes closest to the ancestorial gene with the identified and yet studied forms.

BLAST search for first 100 nucleotides is run to determine the degree of conservance between strains. Values were much lower indicating less matches but the matches were still very much the same types of proteins. This suggests that the first 30 odd amino acids do vary a bit between different species.
