Txawm hais tias feem ntau hom I membrane-bound proteins muaj teeb liab peptides, feem ntau ntawm hom II thiab ntau-spanning membrane-bound proteins yog tsom mus rau txoj kev secretory los ntawm lawv thawj transmembrane domain, uas biochemically zoo li lub teeb liab sib lawv liag tshwj tsis yog tias
Puas peptides ib txwm tau cleaved?
Lwm qhov txawv txav thiab tseem ceeb ntawm cov proteins hauv nuclear yog tias yuav luag txhua qhov kev ua haujlwm loj ntawm cov molecules tseem muaj lawv cov teeb liab peptides, xws li muaj tsis muaj cleavage ntawm thaj tsam teeb liab no thaum xa mus rau hauv lub nucleus..
Puas yog cov cim qhia ib txwm raug tshem tawm?
Cov cim qhia tsis tau ib txwm pom ntawm cov polypeptides ua tiav hauv cov hlwb, txhais tau hais tias cov teeb liab sib lawv liag yog cleaved los ntawm cov protein thaum nws tseem loj hlob ntawm ribosome.
qhov teeb meem peptidase cleave qhov twg?
Signal peptidases yog cov membrane proteases uas ua lub luag haujlwm tseem ceeb hauv kev thauj cov protein ntawm cov kab mob. Lawv cleave tawm lub teeb liab peptide los ntawm precursor proteins uas yog membrane tso los ntawm SecYEG los yog Tat translocons.
Peptides puas tau txais txiaj ntsig?
Lub teeb liab peptide ntawm PTHrP muaj ntau yam qauv qauv, uas yog evolutionarily zoo-conserved ntawm cov tsiaj tsiaj tab sis tsis zoo rau nws ER lub hom phiaj thiab / lossis kev hloov pauv (Fig.
Pom zoo:
Nyob rau hauv pob liab liab liab liab yog?
Cov cim qhia thiab cov tsos mob uas ua rau liab liab ua npaws nws lub npe suav nrog: liab pob liab. Cov pob khaus zoo li lub hnub ci thiab zoo li cov ntawv xuab zeb. Nws feem ntau pib ntawm lub ntsej muag lossis caj dab thiab kis mus rau lub cev, caj npab thiab txhais ceg .
Kuv puas yuav txhawj xeeb txog cov ntshav liab liab hauv cov quav?
Ntshav hauv koj cov quav yuav zoo li ceeb, tab sis feem ntau tsis muaj laj thawj txhawj. Txawm li cas los xij, muaj cov xwm txheej thaum cov ntshav liab liab nyob rau hauv cov quav lossis tsaus dua, cov ntshav laus tuaj yeem yog qhov cim qhia ntawm qee yam hnyav thiab nws yog qhov zoo tshaj plaws mus ntsib koj tus kws kho mob kom kuaj xyuas .
Puas yog lub teeb liab lossis lub teeb liab?
As adjective qhov txawv ntawm chappy thiab choppy yog tias chappy yog tag nrho ntawm chaps; cleft; qhov khoob; qhib thaum choppy yog (ntawm cov dej saum npoo av) muaj ntau me me, ntxhib nthwv dej . Chappy txhais li cas? [chiefly British]
Puas yog ntshav liab liab tshwm sim ib txwm?
Vim tias nws muaj cov hlab ntsha, nws tuaj yeem los ntshav tau yooj yim thaum nthuav dav. Qhov koj pom hauv cov ntshav yog cov ntshav los ntawm koj lub tsev me nyuam, sib xyaw nrog cov hnoos qeev los ntawm cov hnoos qeev los ntawm cov hnoos qeev Pleev Cov hnoos qeev yog cov hnoos qeev uas ua rau hauv lub ncauj tsev menyuam thaum ntxov Nws tiv thaiv kab mob los yog kab mob nkag mus rau hauv koj lub tsev menyuam thiab ncav cuag koj tus menyuam.
Vim li cas cov teeb meem hauv cheeb tsam nuclear tsis cleaved?
Nuclear localization signals tsis raug tshem tawm tom qab thauj mus rau hauv lub nucleus. Qhov no yog qhov xav tau vim nuclear proteins yuav tsum tau xa rov qab, ib zaug tom qab txhua lub cell faib . Dab tsi yog ob qho laj thawj uas yuav ua rau lub chaw teeb tsa nuclear hauv cheeb tsam NLS tsis raug tshem tawm rau cov proteins nuclear?
