Savoy cabbage and unusual seasonings such as juniper. Signs of desirable quality include cabbage that is heavy for its size with leaves that are unblemished and have a bright, fresh look. Peak season for most cabbages in the Northern Hemisphere runs from November through April. Fresh whole cabbage will keep in the refrigerator for one to six weeks depending on type and variety. Hard green, white or red cabbages will keep the longest while the looser Savoy and Chinese varieties such as napa and bok choy need to be consumed more quickly. It is necessary to keep the outer leaves intact without
BOK (gene) of Bok to its interacting partners seems to be mediated by its BH3 domain. The splice variant Bok-S lacks this domain and is unable to form heterodimers with other proteins of the Bcl-2 family. In yeast two-hybrid experiments, Bok was found to interact with the anti-apoptotic proteins Mcl-1, BHRF-1, and Bfl-1. However, interactions with other anti-apoptotic proteins such as Bcl-2, Bcl-xL, and Bcl-w were not detectable (1). Later studies aimed at confirming an interaction between Bok and pro-apoptotic Bak or Bax but were not successful. Accordingly, coexpression of anti-apoptotic proteins such as Mcl-1 suppresses apoptosis induced by Bok overexpression. Consistent
