Bok choy Bok choy Bok choy, pak choi or pok choi (; "Brassica rapa" subsp. "chinensis") is a type of Chinese cabbage. "Chinensis" varieties do not form heads and have smooth, dark green leaf blades instead, forming a cluster reminiscent of mustard greens or celery. "Chinensis" varieties are popular in southern China and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. This group was originally classified as its own species under the name "Brassica chinensis" by Linnaeus. Other than the ambiguous term "Chinese cabbage", the most widely used name in North America for the "chinensis" variety is "bok choy"
BOK (gene) Bcl-2 protein family. The mouse homologue of Bok is called Matador (Mtd). This name is derived from the Latin term mactator which means butcher or killer. Additionally, homologous proteins were found in "Drosophila melanogaster" (fruit fly) and "Gallus gallus" (chicken). The human BOK promoter is activated by the overexpression of members of the E2F hand transcription factor family. Typically, these transcription factors are involved in the promotion of S-phase, so there might be a connection between Bok expression and cell cycle progression. Due to this regulation of Bok expression by the cell cycle, it was proposed that Bok sensitizes growing
