Bok choy (from the Cantonese, literally meaning "white vegetable"; also spelled "pak choi", "bok choi", and "pak choy"). In the UK and South Africa, the term "pak choi" is used. Less commonly, the descriptive English names "Chinese chard", "Chinese mustard", "celery mustard", and "spoon cabbage" are also employed. In Australia, the New South Wales Department of Primary Industries has redefined many transcribed names to refer to specific cultivars. In addition, they have introduced the word "buk choy" to refer to a specific kind of cabbage distinct from "pak choy". In China, the majority of Chinese speak Mandarin (about 955 million people), and
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
