A part of the 3'-flanking region of BP-II gene, which is one of Trimer
esurus flavoviridis venom gland phospholopase A(2) (PLA(2)) isozyme ge
nes, has a region homologous to avian chicken repeat 1 (CR1)-element.
In the present study, ten CR1-like elements were further identified in
T. gramineus venom gland PLA(2) isozyme genes, T. flavoviridis PLA(2)
inhibitor (PLI) genes, and T. flavoviridis and T. gramineus TATA-box
binding protein (TBP) genes. Southern blot analysis using a probe for
CR1 showed that Crotalinae snake genomes contain a number of CR1-like
elements. (C) 1998 Elsevier Science Ltd. All rights reserved.
