Neuroblastoma Breakpoint Family, Member 7 (NBPF7)

NBPF7, Belongs to the NBPF family. The NBPF genes have a repetitive structure with high intragenic and intergenic sequence similarity in both coding and noncoding regions. These similarities might expose these genomic regions to illegitimate recombination, resulting in structural variation in the NBPF genes.  Strikingly, no discernable orthologues could be identified in the completed genomes of fruit fly, nematode, mouse, or rat, but sequences with low homology could be isolated from the draft canine and bovine genomes. Interestingly, this gene family shows primate-specific duplications that result in species-specific arrays of NBPF homologous sequences. Overall, this novel NBPF family reflects the continuous evolution of primate genomes that resulted in large physiological differences, and its potential role in this process is discussed.
