Proteome data for C. elegans and C. remanei. Un-activated spermatid, membranous organelle, and active sperm proteome data for both species analyzed, including WormBase gene identifiers, protein abundances, and peptide coverage. (XLSX 64 kb

Additional file 4: of Proteomic and evolutionary analyses of sperm activation identify uncharacterized genes in Caenorhabditis nematodes

Consensus sequence alignments for the Nematode-Specific Peptide family, group D (NSPD). The amino acid sequence is largely conserved, except for the species-specific amino acid repeats in the middle of the gene. (PDF 79 kb

Additional file 1: of Proteomic and evolutionary analyses of sperm activation identify uncharacterized genes in Caenorhabditis nematodes

The un-activated sperm proteome of C. elegans. The majority of the proteome is comprised of the Nematode-Specific Peptide family, group D (NSPD) and the Major Sperm Protein (MSP). Protein abundance is shown as the relative mean normalized spectrum abundance frequency. Proteins found to be unique to either the membranous organelle or activated sperm proteomes are highlighted in teal, while proteins found in both proteomes are shown in gray. Proteins shown in white were not identified in the membranous organelle or activated sperm proteomes, but were found in the previously published un-activated spermatid proteome of Ma et al. [21].

An unrooted maximum likelihood phylogeny for the Nematode-Specific Peptide family, group D (NSPD). Genes tend to cluster within species and do not recapitulate an evolutionary history of gene orthology. Asterisks denote bootstrap values greater than 80%. (PDF 945 kb
