[HTML][HTML] Loss of the putative RNA-directed RNA polymerase RRF-3 makes C. elegans hypersensitive to RNAi
F Simmer, M Tijsterman, S Parrish, SP Koushika… - Current biology, 2002 - cell.com
RNA interference (RNAi) is a broadly used reverse genetics method in C. elegans [1].
Unfortunately, RNAi does not inhibit all genes [2, 3]. We show that loss of function of a putative …

A post-docking role for active zone protein Rim
SP Koushika, JE Richmond, G Hadwiger… - Nature …, 2001 - nature.com
Rim1 was previously identified as a Rab3 effector localized to the presynaptic active zone in
vertebrates. Here we demonstrate that C. elegans unc-10 mutants lacking Rim are viable, …

“JIP” ing along the axon: the complex roles of JIPs in axonal transport
SP Koushika - Bioessays, 2008 - Wiley Online Library
JIPs are JNK interacting proteins and bind to JNK cascade kinases. JIP1 and JIP3 were
known to be adaptors linking cargo to Kinesin‐I, a major molecular motor for axonal transport. …
