Abstract

A LIM protein gene homologue of the CRP (cysteine­rich protein) family in the whiter-spotted flower chafer, Protaetia brevitarsis, was cloned. The P. brevitarsis LIM protein cDNA encodes a 92 amino acid polypep­tide with a predicted molecular mass of 10,030 Da and a pI of 8.57. The P. brevitarsis LIM protein contains the cysteine-rich consensus sequence of LIM domain and the glycine-rich consensus sequence observed in the cysteine-rich protein family 1 (CRPl). The potential nuclear targeting signal is retained. The deduced amino acid sequence of the P. brevitarsis LIM protein cDNA showed 92$\%$ identity to another beetle, Apriona germari LIM protein. Northern blot analysis showed that P. brevitarsis LIM protein is highly expressed in epidermis and midgut, but not in the fat body.
