CACNA1F

A gene on chromosome Xp11.23 that encodes the alpha-1F subunit of a voltage-dependent calcium channel, which mediates the entry of calcium ions into excitable cells. These channels are also involved in various calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and apoptosis. CACNA1F gives rise to long-lasting (L-type) calcium channels that belong to the high-voltage activated (HVA) group; they are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines and by omega-agatoxin-IIIA.

Molecular pathology
Defects in CACNA1F cause Aaland Island eye disease, cone-rod dystrophy X-linked type 3, and congenital stationary night blindness type 2A.

World At War has its moments, but for anyone who has played COD4, the two games are miles apart.
Whereas COD4 featured a constant corralling of your direction, all too often this is ignored and fails to mask the game's linearity, which detracts from its life.
For a world war simulator, the weapons are surprisingly varied and balanced, which is great news for the death match fans who grumbled about the lack of weapon balancing in COD4.
