A novel subunit of axonemal dynein conserved among lower and higher eukaryotes.

abstract：:The bacterial cell wall muramyl dipeptides MDP and glucosaminyl-MDP (GMDP) are powerful immunostimulators but their binding target remains controversial. We previously reported expression cloning of GMDP-binding polypeptides and identification of Y-box protein 1 (YB-1) as their sole target. Here we show specific bindi...

The ATM1 gene of the yeast Saccharomyces cerevisiae encodes an ABC protein, which is localized to the mitochondrial inner membrane. A deletion of ATM1 results in the accumulation of up to a 30-fold excess of mi...

Despite their discovery as tumor suppressors, we demonstrated that all these proteins are phospholipid-metabolizing enzymes, such as phospholipase (PL) A1 /A2 and acyltransferase. We thus proposed to rename HRASLS1-5 as PLA/ac...
