Tyrosine-protein kinase, or Bromodomain adjacent to zinc finger domain, 1B (BAZ1B) is an enzyme that in humans is encoded by the BAZ1B gene. [5] [6] [7]
This gene encodes a member of the bromodomain protein family. The bromodomain is a structural motif characteristic of proteins involved in chromatin-dependent regulation of transcription. This gene is deleted in Williams-Beuren syndrome, a developmental disorder caused by deletion of multiple genes at 7q11.23. [7]
BAZ1B has been found to affect the activity of 448 other genes and is very important in the development of the neural crest and the face. Research suggests that changes in BAZ1B may have been involved in "self-domesticating" humans. [8] [9]
Model organisms have been used in the study of BAZ1B function. A conditional knockout mouse line, called Baz1btm2a(KOMP)Wtsi, [10] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute. [11] [12] [13]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. [13] [14] [15] [16]

Solute carrier family 41, member 3 is a protein that in humans is encoded by the SLC41A3 gene.
Phospholipase B domain containing 1 is a protein that in humans is encoded by the PLBD1 gene.
Rho GTPase activating protein 25 is a protein that in humans is encoded by the ARHGAP25 gene. The gene is also known as KAIA0053. ARHGAP25 belongs to a family of Rho GTPase-modulating proteins that are implicated in actin remodeling, cell polarity, and cell migration.
Glutamyl-tRNA(Gln) amidotransferase, subunit C homolog (bacterial) is a protein that in humans is encoded by the GATC gene. The gene is also known as 15E1.2 and encodes part of a Glu-tRNA(Gln) amidotransferase enzyme.
Zinc finger protein 367 is a protein that in humans is encoded by the ZNF367 gene. The human gene is also known as ZFF29 and CDC14B; the orthologue in mice is Zfp367. ZNF367 contains a unique Cys2His2 zinc finger motif and is a member of the zinc finger protein family.
In molecular biology, the WAC domain is a protein domain found on the N-terminus of WSTF protein. Its function is still unknown, but putatively thought to be involved in cell growth. The protein domain has been found to be present in both prokaryotes and eukaryotes
