Putative mouse Kalrn mRNA initiation exons A, B, C and D were identified by homology to the rat and human Kalrn initiation exons [27,28], as described here. Mouse Kalrn exons A, B, and C were identified by comparing the known rat sequences (A: Genbank U88157.1; B: U88156.1; C: AF230644.1) with the mouse genome (July 2007 [NCBI37/mm9]) at http://genome.ucsc.edu/cgi-bin/. The putative mouse Kalrn D initiation exon sequence was from XM_001001454.1, and the putative mouse ΔKalrn initiation exon sequence was from ENSMUST00000114949. The A, B, and C sequences all fit the current Ensembl sequences, and C is also a Refseq entry: NM_177357.
