Lesson plan
Brdt
Bromodomain testis-specific protein is a protein that in humans is encoded by the BRDT gene. It is a member of the Bromodomain and Extra-terminal motif (BET) protein family. BRDT is similar to the RING3 protein family. It possesses 2 bromodomain motifs and a PEST sequence (a cluster of proline, glutamic acid, serine, and threonine residues), characteristic of proteins that undergo rapid intracellular degradation. The bromodomain is found in proteins that regulate transcription. Two transcript variants encoding the same protein have been found for this gene. The use of three different mouse models (Brdt knock-out mice, mice expressing a non-functional Brdt and mice expressing a mutated Brdt lacking its first bromodomain) showed that Brdt drives a meiotic and post-meiotic gene expression program. It also controls the genome-wide post-meiotic genome reorganization that occurs after histone hyperacetylation in elongating spermatids.
