POU domain proteins represent a subfamily of homeodomain-containing transcription factors that are expressed in many animal orders in a number of distinct regions in the developing and adult organism. In mammals, the expression profiles of these factors have suggested roles for class I, class III, and class IV POU domain proteins in the development, maintenance, and function of the endocrine and nervous systems. The genetic characterizations of the functions of these proteins during the generation, differentiation, and maturation of cells comprising these tissues have revealed a requirement for the individual actions of these transcription factors in the development of various elements of the anterior pituitary, the brain, and the somatosensory, vestibular/cochlear, and visual systems.
