Crystal structure of the nucleoporin Nup214 in complex with the DEAD-box helicase Ddx19

Template:ABSTRACT PUBMED 19208808

Disease

[NU214_HUMAN] Note=A chromosomal aberration involving NUP214 is found in a subset of acute myeloid leukemia (AML); also known as acute non-lymphocytic leukemia. Translocation t(6;9)(p23;q34) with DEK. It results in the formation of a DEK-CAN fusion gene. Note=A chromosomal aberration involving NUP214 is found in some cases of acute undifferentiated leukemia (AUL). Translocation t(6;9)(q21;q34.1) with SET.

Function

[NU214_HUMAN] May serve as a docking site in the receptor-mediated import of substrates across the nuclear pore complex. [DD19B_HUMAN] ATP-dependent RNA helicase involved in mRNA export from the nucleus. Rather than unwinding RNA duplexes, DDX19B functions as a remodeler of ribonucleoprotein particles, whereby proteins bound to nuclear mRNA are dissociated and replaced by cytoplasmic mRNA binding proteins.
