Background

Calreticulin is a multifunctional protein. It acts as a main Ca(2+)-binding (storage) protein in the lumen of the endoplasmic reticulum. Calreticulin binds Ca2+ ions (a second messenger in signal transduction), rendering it inactive. The Ca2+ is bound with low affinity, but high capacity, and can be released on a signal. Located in storage compartments associated with the endoplasmic reticulum, calreticulin also binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the golgi apparatus. The amino terminus of calreticulin interacts with the DNA-binding domain of the glucocorticoid receptor and prevents the receptor from binding to its specific glucocorticoid response element. Calreticulin reduces the binding of androgen receptor to its hormone-responsive DNA element and inhibits androgen receptor and retinoic acid receptor transcriptional activities in vivo, as well as retinoic acid-induced neuronal differentiation. Therefore, calreticulin acts as a significant modulator of the regulation of gene transcription by nuclear hormone receptors.

A Lungful of Freedom
Size: 9.7" x 9.3" x 1.8"
Dateline: The Passenger-Side Footwell of a Toyota Venza, Sunday Night. We spend our lives in sealed metal boxes, hurtling through a thick, invisible soup of our own collective filth. A foul cocktail of exhaust fumes, road dust, tire particles, and whatever strange, pollen-based miasma the world decides to throw at us on any given day. To breathe that poison in, unfiltered, is an act of slow, unwitting suicide. You need a line of defense. A gatekeeper for your own lungs. Enter the Bosch 6055C HEPA Cabin Air Filter. It is not a glamorous part. It is not a performance upgrade that adds horsepower or prestige. It is a simple, pleated rectangle of paper and charcoal, a humble guardian destined to live out its days in a dark plastic cave behind your glovebox. But its mission is a noble one. The replacement process is a moment of pure, unadulterated, five-minute victory over the dealership's service department. You pop open the glovebox, you unclip the old filter tray, and you pull out the old soldier. And what you find is a horror show. A grey, matted testament to the unseen war it has been fighting on your behalf, choked with leaves, dirt, and the ghosts of a thousand diesel trucks. It is the face of the enemy. You unwrap the new Bosch filter. It feels solid, well-made. The pleats are clean and numerous. I laid it side-by-side with the outgoing Denso filter—a brand that supplies the automakers themselves—and I could find no meaningful difference. The quality was equal. The construction, robust. This was no flimsy, cut-rate pretender. This was a serious piece of hardware from a serious company. You slide the clean, white Bosch into the tray, snap it back into its dark little home, and close the glovebox. The deed is done. You have performed a life-saving transplant on your vehicle's respiratory system in less time than it takes to listen to a single pop song. And the value… the value is the sweet, sweet punchline. For a fraction of what a dealership would charge you for the same simple service, you have installed a top-tier, HEPA-grade filter from one of the most respected names in the business. You have guaranteed yourself a clean, breathable bubble of personal space as you navigate the toxic jungle of the modern roadway. This is not just a filter; it's a small, affordable act of rebellion. It’s a declaration that you, and you alone, are the master of the air you breathe. It is a simple, effective, and profoundly satisfying piece of gear. Highly recommended.

Great Upgrade to your Cabin Filter. Fits 2018 Subaru Outback
Size: 9.7" x 9.3" x 1.8"
This is a great filter upgrade to your cabin filter. This is better than the Subi standard part. Fits my Subaru outback. NOTE: Subi marks their filter with an 'up' arrow; however, this filter is marked with a 'airflow' direction. Direction of air flow is toward the blower motor so it will point downward when you install it.
