From: Apolipocrustacein, formerly vitellogenin, is the major egg yolk precursor protein in decapod crustaceans and is homologous to insect apolipophorin II/I and vertebrate apolipoprotein B

Figure 1

Domain architecture of large lipid transfer protein (LLTP) superfamily members. Large lipid transfer (LLT) module [15] also referred to as Vitellogenin_N and LPD-N domain, DUF1081, and VWD domains are indicated from the N-terminal to the C-terminal ends of the proteins. LLTP families are 1) APO family including vertebrate apolipoprotein B (apoB), decapod crustacean apolipocrustacein (apoCr), and insect apolipophorin II/I (apoLp-II/I) subfamilies, 2) Vtg/CP family including vitellogenin (Vtg) and crustacean clotting protein (CP) subfamilies, and the large subunit of microsomal triglyceride transfer protein (MTP) family.
