Descriptor Spanish: Factor de Transcripción 1 de la Leucemia de Células Pre-B
Descriptor factor de transcripción 1 de la leucemia de células pre-B
Entry term(s) proteína Homeobox PBX1
proteína homeobox 1 de la leucemia de células pre-B
Scope note: Proteína con homeodominio tipo TALE y factor de transcripción que une la secuencia 5'-ATCAATCAA-3' del ADN. Forma un heterodímero con el FACTOR DE TRANSCRIPCIÓN MEIS1 y funciona como activador transcripcional de la PROTEÍNA HOMEOBOX NKX-2.5 y de la ELONGINA A y como represor transcripcional de la PROTEÍNA CDKN2B en la regulación del desarrollo y morfogénesis, como ocurre en el desarrollo del bazo y de los miembros. En algunos casos de LEUCEMIA LINFOCÍTICA AGUDA de células pre-B existen translocaciones cromosómicas que afectan a los genes PBX1 y TCF3.

Scope note: A TALE-type homeodomain protein and transcription factor that binds the DNA sequence 5'-ATCAATCAA-3'. It forms a heterodimer with MEIS1 TRANSCRIPTION FACTOR and functions as a transcriptional activator of HOMEOBOX PROTEIN NKX-2.5 and ELONGIN A, and as a transcriptional repressor of CDKN2B PROTEIN, in the regulation of developmental and morphogenetic processes such as spleen and limb development. Chromosome translocations involving the PBX1 and TCF3 genes occur in cases of pre-B-cell ACUTE LYMPHOID LEUKEMIA.
