hel-1 encodes an ortholog of human 56-kD U2AF65 associated protein (UAP56)that is required for exporting mRNAs from the nucleus; unlike animals withRNAi against several other splicing factors, hel-1(RNAi) animals fail toexport transgenic GFP mRNA from the nucleus; conversely, hel-1overexpression is lethal, with failed transgene expression as well.
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in determination of adult lifespan; nuclear mRNA surveillance; and positive regulation of gene expression. Located in nucleus. Part of transcription regulator complex. Expressed in hypodermis; intestine; and neurons. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Is an ortholog of human DDX39A (DExD-box helicase 39A).
Pseudogene tag removed because the corresponding sequence object for this gene has not been annotated as a pseudogene. This discrepancy may reflect that the sequence object was once a pseudogene and has subsequently been converted into a real gene (without this Locus object being updated). Alternatively it may be that this gene is a pseudogene in another C. elegans strain, but not in the sequenced N2 strain. [krb 030806]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
