Clin Exp Immunol . 2013 Apr; 172(3):500-6. PMID: 23600839
Recent basic and clinical studies have shown that the programmed death ligand (PD-L)/PD-1 pathway has a significant role in tumour immunity, and its blockade has a therapeutic potential against several...

Hotta K, Sho M, Fujimoto K, Shimada K, Yamato I, Anai S, et al.
Br J Cancer . 2011 Sep; 105(8):1191-6. PMID: 21934683
Background: Memory T cells are well known to have a critical role for host defense in humans. However, their role in actual human cancer remains largely unknown. In this study,...

Br J Cancer . 2009 Oct; 101(10):1709-16. PMID: 19844235
Background: B7-H3 is a new member of the B7 ligand family and regulates T-cell responses in various conditions. However, the role of B7-H3 in tumour immunity is largely unknown. The...

Tabata K, Kajiyama M, Hiraishi T, Abe H, Yamato I, Doi Y
Biomacromolecules . 2002 Jan; 2(4):1155-60. PMID: 11777387
Poly(aspartic acid) (PAA) hydrolase was purified from Sphingomonas sp. KT-1 (JCM10459). The purified hydrolase degraded thermally synthesized PAA to oligomers. The molecular mass of PAA hydrolase was 30 kDa and...

V-type Na(+)-ATPase of Enterococcus hirae binds about six (6 +/- 1) Na(+) ions/enzyme molecule with a high affinity (Murata, T., Igarashi, K., Kakinuma, Y., and Yamato, I. (2000) J. Biol....

Murata T, Kawano M, Igarashi K, Yamato I, Kakinuma Y
Biochim Biophys Acta . 2001 Mar; 1505(1):75-81. PMID: 11248190
V-ATPases make up a family of proton pumps distributed widely from bacteria to higher organisms. We found a variant of this family, a Na(+)-translocating ATPase, in a Gram-positive bacterium, Enterococcus...

Murata T, Igarashi K, Kakinuma Y, Yamato I
J Biol Chem . 2000 May; 275(18):13415-9. PMID: 10788452
Rotation catalysis theory has been successfully applied to the molecular mechanism of the ATP synthase (F(0)F(1)-ATPase) and probably of the vacuolar ATPase. We investigated the ion binding step to Enterococcus...

Takase K, Yamato I, Igarashi K, Kakinuma Y
Biosci Biotechnol Biochem . 1999 Jul; 63(6):1125-9. PMID: 10427702
Enterococcus hirae vacuolar ATPase catalyzes translocation of Na+ or Li+ coupled with ATP hydrolysis. It is suggested that the glutamic acid residue (Glu139) of NtpK proteolipid subunit of this multisubunit...

FEBS Lett . 1999 Jul; 454(1-2):67-70. PMID: 10413097
The Enterococcus hirae ntp operon encodes both a vacuolar ATPase, which transports Na+ as well as Li+, and the KtrII K+ transporter. A plasmid, in which the chloramphenicol acetyltransferase gene...

Kakinuma Y, Yamato I, Murata T
J Bioenerg Biomembr . 1999 May; 31(1):7-14. PMID: 10340844
A Na+-translocating ATPase was discovered in a gram-positive bacterium Enterococcus hirae. Our biochemical and molecular biological studies revealed that this Na+-ATPase belongs to the vacuolar-type enzyme. Purified Na+-ATPase consisted of...
