... and a new family member?

Bovine stefin C, a new member of the stefin family.

Four low M(r) cysteine proteinase inhibitors with different pI values were isolated from bovine thymus using alkaline activation of the gland homogenate, affinity chromatography on carboxymethyl-papain-Sepharose, gel filtration on Sephadex G-50, ion-exchange chromatography on a DEAE-cellulose column and a fast protein liquid chromatography Mono Q column, and hydrophobic chromatography on a TSK ...

phyB of tobacco, a new member of the phytochrome family.

Phytochrome plays a central role in the light-dependent regulation of photomorphogenesis such as seed germination, stem growth, and floral induction as well as chloroplast development and anthocyanin synthesis. This photoreceptor has been shown to modulate the pattems of expression for many plant genes (Nagy et al., 1988; Quail, 1991). Plants synthesize the physiologically inactive, red-light a...

Genome Stability: A New Member of the RFC family

Three distinct forms of replication factor C are known to play vital roles in genome replication and integrity in eukaryotic cells. A fourth such complex has recently been identified; initial results suggest that this new family member plays an important role during S phase.

A new family member for gonadotropin-releasing hormone.

The two living representatives of the most ancient vertebrates, Agnathans, are lamprey and hagfish. Using immunological methods, we identified gonadotropin-releasing hormone (GnRH)-like molecules in the lamprey brain, but not hagfish. The lamprey GnRH was detected poorly by antisera directed at the C-terminus, suggesting that a C-terminal amino acid substitution may have occurred in the lamprey...
