Orai1 is an essential pore subunit of the CRAC channel

M Prakriya, S Feske, Y Gwack, S Srikanth, A Rao… - Nature, 2006 - nature.com
Stimulation of immune cells causes depletion of Ca 2+ from endoplasmic reticulum (ER)
stores, thereby triggering sustained Ca 2+ entry through store-operated Ca 2+ release-activated …

A mutation in Orai1 causes immune deficiency by abrogating CRAC channel function

S Feske, Y Gwack, M Prakriya, S Srikanth, SH Puppel… - Nature, 2006 - nature.com
Antigen stimulation of immune cells triggers Ca 2+ entry through Ca 2+ release-activated
Ca 2+ (CRAC) channels, promoting the immune response to pathogens by activating the …

STIM1–Orai1 interactions and Orai1 conformational changes revealed by live‐cell FRET microscopy

…, D Ren, RJ Miller, M Prakriya - The Journal of …, 2008 - Wiley Online Library
Ca 2+ entry through store‐operated Ca 2+ release‐activated Ca 2+ (CRAC) channels
initiates key functions such as gene expression and exocytosis of inflammatory mediators. …

Regulation of CRAC channel activity by recruitment of silent channels to a high open-probability gating mode

M Prakriya, RS Lewis - The Journal of general physiology, 2006 - rupress.org
CRAC (calcium release-activated Ca 2+ ) channels attain an extremely high selectivity for
Ca 2+ from the blockade of monovalent cation permeation by Ca 2+ within the pore. In this …

Store-operated calcium channels

M Prakriya, RS Lewis - Physiological reviews, 2015 - journals.physiology.org
Store-operated calcium channels (SOCs) are a major pathway for calcium signaling in virtually
all metozoan cells and serve a wide variety of functions ranging from gene expression, …

[PDF][PDF] Mitochondria are required for antigen-specific T cell activation through reactive oxygen species signaling

LA Sena, S Li, A Jairaman, M Prakriya, T Ezponda… - Immunity, 2013 - cell.com
It is widely appreciated that T cells increase glycolytic flux during activation, but the role of
mitochondrial flux is unclear. Here, we have shown that mitochondrial metabolism in the …

Dual functions for the endoplasmic reticulum calcium sensors STIM1 and STIM2 in T cell activation and tolerance

…, S Sharma, E Lamperti, W Chung, M Prakriya… - Nature …, 2008 - nature.com
Store-operated Ca 2+ entry through calcium release–activated calcium channels is the chief
mechanism for increasing intracellular Ca 2+ in immune cells. Here we show that mouse T …
