Mouse dynein intermediate chain splice isoforms.

The mouse gene nomenclature convention is to name each isoform: genename_GenBank transcript number. We have used the unofficial names Dync1i1.A, Dync1i1.B, etc., here to show their correspondence to the widely used IC 1A, 1B, 1C previously described in rat [22]. However, we also show the correspondence to GenBank mouse cDNAs, UCSC known genes and Ensembl transcripts. As Dync1i2 has two alternative non-coding first exons, we cannot determine which Dync1i2 isoforms correspond to the previously described rat isoforms IC2A, 2B, 2C, hence these are in parentheses [22]. Crackower and colleagues noted the presence of some mouse splice isoforms and we also show to their notation from their 1999 publication Dnci1a, c, d, e in italics [34]. We number exons from 1 to 17 for Dync1i1, and from 1 to 18 for Dync1i2 including either exon 1a or exon 1b, and exon 3b. *first described in this paper.
