Post-diapause synthesis of ArHsp40-2, a type 2 J-domain protein from Artemia franciscana, is developmentally regulated and induced by stress.

ABSTRACT: Post-diapause cysts of Artemia franciscana undergo a well-defined developmental process whereby internal differentiation leads to rupture of the cyst shell, release of membrane-enclosed nauplii and hatching to yield swimming larvae. The post-diapause development of A. franciscana has been examined at biochemical and molecular levels, yet little is known about molecular chaperone function during this process. In addressing this we recently described ArHsp40, a type 1 J-domain protein in post-diapause A. franciscana cysts and larvae. The current report describes ArHsp40-2, a second J-domain protein from A. franciscana. ArHsp40-2 is a type 2 J-domain protein, lacking a zinc binding domain but containing other domains characteristic of these proteins. Notably, ArHsp40-2 possesses a double barr
