STRUCTURE OF BTB/POZ TRANSCRIPTION REPRESSION DOMAIN FROM PROMELOCYTIC LEUKEMIA ZINC FINGER ONCOPROTEIN

Template:ABSTRACT PUBMED 10537309

Disease

[ZBT16_HUMAN] Defects in ZBTB16 are the cause of skeletal defects genital hypoplasia and mental retardation (SGYMR) [MIM:612447]. A disorder characterized by mental retardation, craniofacial dysmorphism, microcephaly and short stature. Additional features include absence of the thumbs, hypoplasia of the radii and ulnae, additional vertebrae and ribs, retarded bone age and genital hypoplasia.[1] Note=A chromosomal aberration involving ZBTB16 may be a cause of acute promyelocytic leukemia (APL). Translocation t(11;17)(q32;q21) with RARA.

Function

[ZBT16_HUMAN] Probable transcription factor. May play a role in myeloid maturation and in the development and/or maintenance of other differentiated tissues. Probable substrate-recognition component of an E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins.[2]
