Plasma Membrane Ca2+ Pump in Rat Brain
The expression at the protein level of plasma membrane calcium pump (PMCA) isoforms in rat brain was detected by new antibodies that distinguished the four gene products and their alternativelyExpand

Plasma Membrane Ca2+ Pump Isoforms 2a and 2b Are Unusually Responsive to Calmodulin and Ca2+ *
The full-length a and b variants of the rat plasma membrane calcium pump, isoform 2 (rPMCA2a and rPMCA2b), were constructed and expressed in COS-7 cells. To characterize these isoforms, calciumExpand

The Rate of Activation by Calmodulin of Isoform 4 of the Plasma Membrane Ca2+ Pump Is Slow and Is Changed by Alternative Splicing*
A reconstitution system allowed us to measure the ATPase activity of specific isoforms of the plasma membrane Ca2+ pump continuously, and to measure the effects of adding or removing calmodulin. TheExpand

Cloning and Molecular Analysis of the Plasma Membrane Ca2+ ‐ATPase Gene in Paramecium tetraurelia
ABSTRACT. We have determined the DNA sequence of the gene encoding the protein of the plasma membrane Ca2+‐ATPase in Paramecium tetraurelia. The predicted amino acid sequence of the plasma membraneExpand

Protein Kinase C Phosphorylates the “a” Forms of Plasma Membrane Ca2+ Pump Isoforms 2 and 3 and Prevents Binding of Calmodulin*
Phosphorylation by protein kinase C of the “a” and “b” variants of plasma membrane Ca2+pump isoforms 2 and 3 was studied. Full-length versions of these isoforms were assembled and expressed in COSExpand

Plasma Membrane Ca2+ Pump Isoform 3f Is Weakly Stimulated by Calmodulin*
Isoform 3f of the plasma membrane Ca2+ pump is a major isoform of this pump in rat skeletal muscle. It has an unusual structure, with a short carboxyl-terminal regulatory region of only 33 residuesExpand

Ca2+ transport and chemoreception in Paramecium
Intracellular Ca2+ levels in Paramecium must be tightly controlled, yet little is understood about the mechanisms of control. We describe here indirect evidence that a phosphoenzyme intermediate isExpand

FINGER FORECASTING: A Pointer to Athletic Prowess in Women A Preliminary Investigation by an Undergraduate Biology Class
With all the technology today, we were surprised to read a recent British study (Paul et al., 2006) that found a connection between the length of a woman's index (2D) and ring (4D) fingers to herExpand
