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.

Publication Abstract from PubMed

The mammalian nuclear pore complex (NPC) is an approximately 120-MDa proteinaceous assembly consisting of approximately 30 proteins and is the sole gate in the nuclear envelope. The human protooncogene Nup214 was first identified as a target for chromosomal translocation involved in leukemogenesis. Nup214 is located on the cytoplasmic face of the NPC and is implicated in anchoring the cytoplasmic filaments of the NPC and recruiting the RNA helicase Ddx19. Here, we present the crystal structure of the human Nup214 N-terminal domain at 1.65-A resolution. The structure reveals a seven-bladed beta-propeller followed by a 30-residue C-terminal extended peptide segment, which folds back onto the beta-propeller and binds to its bottom face. The beta-propeller repeats lack any recognizable sequence motif and are distinguished by extensive insertions between the canonical beta-strands. We propose a mechanism by which the C-terminal peptide extension is involved in NPC assembly.
