A deletion of 15 nt in the first exon, predicted to replace six contiguous amino acids, Ser340-Ala345, with one Thr. This deletion is located within a serine-rich region, in which Ser325, Ser340 and Thr341 have been suggested as targets of Protein Kinase C.
A 15bp deletion that replaces 6 amino acids (Ser340-Ala345) with one Thr. This was one of 23 nucleotide substitutions and 32 indels in the en region in the mutant. The others do not alter the amino acid sequence.
