Genes affected

LYNX1 (HGNC:29604): (Ly6/neurotoxin 1) This gene encodes a GPI-anchored, cell membrane bound member of the Ly6/uPAR (LU) superfamily of proteins containing the unique three-finger LU domain. This protein interacts with nicotinic acetylcholine receptors (nAChRs), and is thought to function as a modulator of nAChR activity to prevent excessive excitation. Alternatively spliced transcript variants have been found for this gene. Read-through transcription between this gene and the neighboring downstream gene (SLURP2) generates naturally-occurring transcripts (LYNX1-SLURP2) that encode a fusion protein comprised of sequence sharing identity with each individual gene product.

LYNX1 links:

LYNX1-SLURP2 (HGNC:52291): (LYNX1-SLURP2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring LYNX1 and SLURP2 genes. The readthrough transcript encodes a fusion protein comprised of sequence sharing identity with each individual gene product. The significance of this read-through transcription and the function of the resulting protein product have not yet been determined. [provided by RefSeq, Sep 2017]
