Background

E3 ubiquitin-protein ligase (UBE3A) which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and transfers it to its substrates. Several substrates have been identified including the BMAL1, ARC, RAD23A and RAD23B, MCM7 (which is involved in DNA replication), annexin A1, the PML tumor suppressor, and the cell cycle regulator CDKN1B. Additionally, may function as a cellular quality control ubiquitin ligase by helping the degradation of the cytoplasmic misfolded proteins. Finally, UBE3A also promotes its own degradation in vivo. It Plays an important role in the regulation of the circadian clock, leading to its proteasomal degradation. UBE3A acts as transcriptional coactivator of progesterone receptor PGR upon progesterone hormone activation and as a regulator of synaptic development by mediating ubiquitination and degradation of ARC.

Yummy pigs ear
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
These are my dogs "special" treat. These range in size from large to small ears but my dog loves them all the same. Great for heavy chewers.

One-and-done treat for giant breeds (our 186lb foster approves)
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1), Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
We foster a 186lb Saint Bernard, and finding treats that actually satisfy her without requiring half the bag has been a challenge. These pig ears? Game changer. What makes these work: - ONE ear = one satisfied dog (compared to other treats where the bag says “35 per day” and she’d still beg for more) - Keeps her busy for about 5 minutes of focused chewing - She does a little excited dance when she sees the bag—can’t even sit, just wiggles - Zero crumbs or mess because she devours every single bit, then spends the next hour sniffing around hoping another one appears - She immediately grabs it and heads to her favorite bed to settle in—doesn’t move until it’s gone The only “issue”: There’s a bit of oil/greasiness when handling them, but nothing a quick hand wash can’t fix (Mrs. Meyer’s Cucumber soap works great, just saying). Bottom line: If you have a giant breed and you’re tired of buying treats that require multiple servings or disappear in one bite, these are it. One ear, complete satisfaction, Subscribe & Save so they just show up like a present you forgot you ordered. Our girl Ellie gives them 186 pounds of approval.

Size of Ears is Inconsistent
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
A bit disappointing with the size, 1 large pig ear, the rest small and not actual whole pig ears. But Doggo enjoys them. No problems with digestion for him.

Just what the pet parent ordered
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
As a furbaby parent of 2 huskies who are chewers in their first 3 yrs of their life, this product helps a lot. Very healthy, dogs love them, safe, and chewy. Definitely a winner. Love the price for my pockets. Give it a try, you won't be disappointed and your pup will thank you too.

Smell of plastic
Flavor Name: Pig Ears, Size: 12 Count (Pack of 1)
These had a very off-putting smell right out of the bag - each one smelled like plastic, almost as if they’d been sitting in the packaging for too long. My dog wouldn’t touch them at all, which says everything. Would not purchase again.
