SPF1/YEL031W Summary Help

Standard Name SPF1 1
Systematic Name YEL031W
Alias COD1 2 , PIO1 3 , PER9 4
Feature Type ORF, Verified
Description P-type ATPase, ion transporter of the ER membrane; required to maintain normal lipid composition of intracellular compartments and proper targeting of mitochondrial outer membrane tail-anchored proteins; involved in ER function and Ca2+ homeostasis; required for regulating Hmg2p degradation; confers sensitivity to a killer toxin (SMKT) produced by Pichia farinosa KK1 (1, 2, 5, 6)
Name Description Sensitivity to Pichia Farinosa killer toxin 1
