Factors Governing the Na(+) vs K(+) Selectivity in Sodium Ion Channels
|
Monovalent Na(+) and K(+) ion channels, specialized pore-forming proteins that play crucial biological roles such as controlling cardiac, skeletal, and smooth muscle contraction, are characterized by a remarkable metal selectivity, conducting the native cation while rejecting its monovalent contender and other ions present in the cellular/extracellular milieu. |

Receptor guanylyl cyclases in Inka cells targeted by eclosion hormone.
|
A signature of eclosion hormone (EH) action in insect ecdysis is elevation of cGMP in Inka cells, leading to massive release of ecdysis triggering hormone (ETH) and ecdysis initiation. Although this aspect of EH-induced signal transduction is well known, the receptor mediating this process has not been identified. |

Distinct Antiviral Roles for Human 2',5'-Oligoadenylate Synthetase Family Members against Dengue Virus Infection 1
|
The 2`,5`-oligoadenylate synthetase (OAS) and its downstream effector RNase L play important roles in host defense against virus infection. Oas1b, one of the eight Oas1 genes in the mouse genome, has been identified as a murine flavivirus-resistance gene. Four genes, OAS1, OAS2, OAS3, and OAS-like (OASL), have been identified in the human OAS gene family, and 10 isoforms, including OAS1 (p42, p44, p46, p48, and p52), OAS2 (p69 and p71), OAS3 (p100), and OASL (p30 and p59) can be generated by alternative splicing. |

CPAP is a cell-cycle regulated protein that controls centriole length.
|
Centriole duplication involves the growing of a procentriole (progeny centriole) next to the proximal end of each pre-existing centriole (parental centriole). The molecular mechanisms that regulate procentriole elongation remain obscure. We show here that expression of the centriolar protein CPAP (centrosomal P4.1-associated protein) is carefully regulated during the cell cycle, |
