BRN-3 is a group of related transcription factors in the POU family. [1] They are also known as class 4 POU domain homeobox proteins.

Contents

There are three BRN-3 proteins encoded by the following genes:

Nomenclature

The BRN or Brn prefix is an abbreviation for "brain"; the longer name is "Brain-specific homeobox". The name of the group may also be abbreviated as POU4, Pou4, POU IV, or POU-IV.

Homeobox DNA pattern affecting anatomy development

A homeobox is a DNA sequence, around 180 base pairs long, found within genes that are involved in the regulation of patterns of anatomical development (morphogenesis) in animals, fungi, plants, and numerous single cell eukaryotes. Homeobox genes encode homeodomain protein products that are transcription factors sharing a characteristic protein fold structure that binds DNA to regulate expression of target genes. Homeodomain proteins regulate gene expression and cell differentiation during early embryonic development, thus mutations in homeobox genes can cause developmental disorders.
