Both model systems have similar expression of integral membrane proteins at tight junctions but differ in expression of accessory proteins such as ZO-2.
Recently, an accessory protein was also found in the luciferase of Oplophorus (Inouye et al., 2000).
Other accessory proteins necessary for efficient translocation of proteins across the inner membrane, such as YidC protein (RWLH02988), trigger factor, ppiase (RWLH04521) and two ORFs for SecY stabilizing membrane protein (RWLH04883, RWLH05233), were identified.
Defects in the ACTH receptor (MC2R) and accessory proteins can result in adrenal glands unresponsive to ACTH, leading to reduced synthesis of steroid hormones required for downstream developmental events (1).
In this approach, template DNA is mixed with two template-specific primers which are of opposite orientation and flank the region of interest (just as in PCR), along with a DNA helicase, some SSBs, and often (depending on the specific helicase and polymerase), a few other "accessory proteins" which assist the helicase and DNA polymerase in optimum function.
A suite of accessory proteins control how the clutch is engaged, including those that dismantle or 'cut' these polymers, such as ADF1.

"But in nature, the toxin is accompanied by a host of nontoxic accessory proteins. The accessory proteins help protect the natural toxin from harsh conditions in your stomach created by enzymes and by gastric acid."
TOR appears to be the progenitor of a new class of endocytotic accessory proteins. In contrast to the other heterotetrameric and monomeric adaptor protein classes, TOR is a homotetrameric protein.
