Gene prediction based on EST data and similarity to mouse and macaca fascicularis orthologs. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. Wrong choice of CDS. Wrong choice of CDS. Truncated N-terminus.
