Fig. 2. Molecular cloning of mouse sperm PLC
. (A) Clustal alignment of mouse sperm PLC
with rat PLC
1 (Accession number, P10688). Identical amino acids are shown in shaded black boxes, conservative substitutions in grey. (B) Schematic illustrating the predicted domain features of mouse PLC
and mammalian PLC isoforms ß,
,
, and
. (C) Sequence identity (blue) and similarity (red) between mammalian PLC isoforms (ß3, P51432;
2, AAH07565;
1, P10688;
, AAG17145; and
). (D) Dendrogram illustrating phylogeny of Clustal aligned mammalian PLC sequences. Tree branch lengths, indicating amino acid substitutions per residue, were 0.298 for
; 0.309-0.322 for
1-4; 0.397 for
; 0.400-0.413 for ß1-4; and 0.412-0.417 for
1-2.
