This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. It is a subline of b2b1468Clo. The molecular lesion for this subline is attributed to an A to G substitution at coding nucleotide position 5966 in exon 35 of the cDNA (c.5966A>G, NM_010060). This changes the asparagine residue to serine at position 1989 of the encoded protein (p.N1989S). (J:175213)
