RTN1/YDR233C Summary Help

Standard Name RTN1 1
Systematic Name YDR233C
Feature Type ORF, Verified
Description Reticulon protein; stabilizes membrane curvature; involved in nuclear pore assembly and maintenance of tubular ER morphology; mutant overexpressing RTN1 shows increase in tubular ER; interacts with exocyst subunit Sec6p, Yip3p, and Sbh1p; more abundant than Rtn2p; member of the RTNLA subfamily; mutants have reduced phosphatidylserine transfer between the ER and mitochondria; RTN1 has a paralog, RTN2, that arose from the whole genome duplication (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
Name Description ReTiculoN-like 1
