Gene : CEP1 A. thaliana

DB identifier  ? AT5G50260 Secondary Identifier  ? locus:2157712
Name  ? cysteine endopeptidase 1 Brief Description  Cysteine proteinases superfamily protein
TAIR Computational Description  Cysteine proteinases superfamily protein;(source:Araport11)
TAIR Curator Summary  Encodes a papain-like cysteine protease involved in tapetal programmed cell death and pollen development.CEP1 is expressed specifically in the tapetum from stages 5 to 11 of anther development. The CEP1 protein first appears as a proenzyme in precursor protease vesicles, and is then transported to the vacuole and transformed into the mature enzyme before rupture of the vacuole. CEP1 was also released to the tapetal cell wall during late stage 6 and stage 7. After the tapetal cell wall degenerated, the CEP1 enzyme entered the callose wall from the degenerated tapetal cell wall and was probably involved in degeneration of the callose wall.
