From: Functional effects of spinocerebellar ataxia type 13 mutations are conserved in zebrafish Kv3.3 channels

Chromosome Identity 1 Strand N-term. Exon 2 S1-S6 Exon 2 Prox. C-term. Exon 2 Distal C Exon 2 Alt. C Exon 2

  1. 1 Identities were assigned on the basis of the phylogenetic and syntenic analyses shown in Figs. 1-3.
  2. 2 The identified exons encode the N-terminus, the S1-S6 membrane domain, the proximal portion of the C-terminus, and one or more putative sequences for the distal C-terminus, which may be alternatively spliced. The numbers correspond to the chromosomal positions of each exon.
  3. 3 According to Zv8, there is an additional exon encoding a Kv3 N-terminus on chromosome 4 (minus strand) at position 2,762,001. Because previous genome releases contained stray Kv3 exons that disappeared in subsequent releases, this exon is likely to reflect an assembly error (data not shown).
  4. 4 In Zv8, the N-terminal exon of kcnc3b (italics) is out of order compared to the other exons.
  5. 5 In Zv8, the distal C-terminal exon of kcnc3b has been mapped to the plus strand, in contrast to the other exons.
