ENU mutagenesis resulted in a nucleotide substitution of A to T at the end of intron 5 that reduces the effectiveness of the splice acceptor site and leads to the insertion of 57 bp at the beginning of exon 6. The inserted base pairs add 19 amino acids to the coded protein and produce an additional loop near the carboxyl terminus. (J:136138)
