Receptors yog feem ntau transmembrane cov proteins , uas khi rau signaling molecules sab nraum lub xovtooj ntawm tes thiab tom qab ntawd xa cov teeb liab los ntawm ib ntu ntawm cov hloov pauv molecular mus rau hauv cov kev taw qhia sab hauv. Ib qho acetylcholine tus neeg txais kev pab (ntsuab) tsim ib qho gated ion channel hauv plasma membrane.

Kuj nug, dab tsi yog qhov ua haujlwm ntawm receptor protein?

Receptors yog cov proteins lossis glycoprotein uas khi cov cim qhia cov khoom siv hu ua thawj cov tub txib, lossis ligands. Lawv tuaj yeem pib qhov kev taw qhia cascade, lossis tshuaj teb, uas ua rau cell kev loj hlob, kev faib, thiab kev tuag los yog qhib cov hlab ntsha.

Ib sab saum toj, yuav ua li cas yog tias receptor protein hloov pauv? Cov qauv kev hloov pauv provoked los ntawm kev hloov pauv los yog variations nyob rau hauv cov noob coding rau GPCRs tej zaum yuav ua rau misfolding, hloov plasma membrane qhia ntawm lub receptor protein thiab nquag mus rau kab mob.

Tom qab ntawd, dab tsi yog qhov piv txwv ntawm receptor protein?

Piv txwv ntawm cov protein receptor / cov receptors suav: a. Guanine nucleotide-binding protein ntau - ua ke cov receptors (GPCRs) (metabotropic). b. serine threonine kinases (SerThr Kinase): TGF-β; MAPK cascade; phosphoinositol kinase-related kinase (PIKK) tsev neeg - mTOR (FRAP1), ATM, ATR, DNA-PK.

Cov protein thauj khoom ua li cas?

Thauj cov proteins ua qhov rooj rau lub cell , pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua tus neeg nyob cell . Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration.
