Organization and sequence comparison of B. germanica LpR. A) BgLpR shows the organization and characteristic domains of a LDL receptor. Two isoforms of BgLpR were found, differing by an insertion/deletion of 24 aa in the O-sugar linked domain. B) Comparison of modular domains between different insect LpRs. Identity (%) with respect to B. germanica sequence is indicated (overall identity indicated below the species name, and domain identity indicated below the corresponding domain). The complete binomial name of the species can be found in the corresponding section of Methods.
