Kev tsis sib xws membrane proteins suav nrog transmembrane cov proteins thiab lipid-txheej txheem cov proteins . Ob hom ntawm daim nyias nyias -spanning domains yog pom hauv transmembrane cov proteins : ib los yog ntau tshaj α helices los yog, feem ntau tsawg, ntau β strands (raws li nyob rau hauv porins).

Ntawm no, nyob qhov twg cov proteins pom nyob rau hauv lub cell membrane?

Peripheral membrane proteins yog pom nyob rau sab nraud thiab sab hauv ntawm daim nyias nyias , txuas nrog rau ib qho cov proteins los yog phospholipids. Tsis zoo li ib qho membrane proteins , peripheral membrane proteins tsis txhob lo rau hauv cov tub ntxhais hydrophobic ntawm lub daim nyias nyias , thiab lawv zoo li yuav ua tau yooj yim dua.

Tsis tas li ntawd, 5 hom membrane proteins yog dab tsi? 1 Teb

  • thauj cov protein. Cov transmembrane proteins tuaj yeem tsim cov pore lossis channel hauv daim nyias nyias uas yog xaiv rau qee cov molecules.
  • Enzymes. Cov proteins no muaj cov haujlwm enzymatic.
  • Teeb liab transduction proteins.
  • Paub cov proteins.
  • Koom nrog cov protein.
  • Daim ntawv txuas.

Hais txog qhov no, dab tsi yog 3 hom proteins uas tuaj yeem pom hauv cell membrane?

Raws li lawv cov qauv, muaj lub ntsiab peb hom ntawm membrane proteins : thawj tus yog integral daim nyias nyias protein uas yog nyob mus ib txhis anchored los yog ib feem ntawm lub daim nyias nyias , ob hom yog peripheral daim nyias nyias protein uas tsuas yog txuas rau ib ntus rau lipid bilayer lossis rau lwm qhov sib xyaw cov proteins , thiab peb

Vim li cas cov protein muaj nyob hauv cell membranes?

Membrane proteins ua ntau yam haujlwm tseem ceeb rau kev ciaj sia ntawm cov kab mob: Membrane tus neeg txais kev pab cov proteins relay teeb liab ntawm lub cell cov sab hauv thiab sab nraud ib puag ncig. Kev thauj mus los cov proteins txav molecules thiab ions hla lub daim nyias nyias . Cell adhesion molecules tso cai hlwb los txheeb xyuas thiab sib tham.
