Background

Cullin-4A (CUL4A) is a core component of multiple cullin-RING type Ubiquitin ligase complexes that mediate the ubiquitination of proteins involved in cell cycle progression, DNA repair and other processes.  In the DCX complex (DDB1-CUL4-X-box), CUL4A serves as a scaffold that organizes the DDB1-X-box substrate recognition subunits with the RBX1 subunit and contributes to catalysis through positioning of the substrate and an E2 ubiquitin-conjugating enzyme.  In vivo, the E3 ubiquitin ligase activity of the DCX complex is dependent on neddylation of the CUL4 subunit, though neddylation may be dispensable in some in vitro reactions.

Will probably be destroyed soon, but SUPER CUTE!
Color: Pink Purse, Size: One Size
Super cute! It will probably eventually be ripped to shreds by my pups soon because it is not as sturdy as other toys out there. It is also pretty small so not the best for large dogs destructive dogs. My lab tries to eat it and rip it but my small chihuahua plays with it and fetches it (she also looks adorable holding it her mouth!!)

Leave a toy for the dog when going to work, and no housebreaking when coming back
Color: Purple-Blue, Size: 2pcs
The dog is quite clingy. Every time it sees me put on my shoes to go out, it gets nervous. Since having this bear around, when it goes out, its attention is all on the toys, and when it comes back home, its mood has become much more stable.
