Biology:GLE1L
Generic protein structure example |
Nucleoporin GLE1 is a protein that in humans is encoded by the GLE1 gene on chromosome 9.[1][2][3]
Function
This gene encodes a predicted 75-kDa polypeptide with high sequence and structure homology to yeast Gle1p, which is nuclear protein with a leucine-rich nuclear export sequence essential for poly(A)+RNA export. Inhibition of human GLE1L by microinjection of antibodies against GLE1L in HeLa cells resulted in inhibition of poly(A)+RNA export. Immunoflourescence studies show that GLE1L is localized at the nuclear pore complexes. This localization suggests that GLE1L may act at a terminal step in the export of mature RNA messages to the cytoplasm. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene.[3]
Clinical significance
A genome-wide screening and linkage analysis assigned the disease locus of lethal congenital contracture syndrome, one of 40 Finnish heritage diseases, to a defined region of 9q34, where the GLE1 gene is located.[4] Mutations in GLEI have been identified in families with foetal motoneuron disease.[5]
Interactions
GLE1L has been shown to interact with NUP155.[6]
