Zonula adherens yog tsim los ntawm ntau yam proteins: Cov actin microfilaments ntawm cytoskeleton (cov pob txha sab hauv ntawm lub cell). Anchor proteins, pom nyob rau hauv txhua lub cell. Cov no yog hu ua alpha-catenin, beta-catenin, gamma-catenin (aka plakoglobin), vinculin, thiab alpha-actinin.
Dab tsi yog cov kev sib txuas ua ke ua ke ntawm?
Adherens junctions yog suav nrog tus tib kis transmembrane protein, E-cadherin Lub npe extracellular tau npaj los tsim kev sib cuam tshuam nrog E-cadherin ntawm cov nyob sib ze. Lub intracellular domain muaj ob thaj tsam khi; juxtamembrane domain (JMD) thiab catenin binding domain (CBD).
Zonula adherence yog dab tsi?
Adherens junctions (los yog zonula adherens, nruab nrab junction, los yog "siv desmosome") yog protein complexes uas tshwm sim ntawm cell-cell junctions, cell-matrix junctions nyob rau hauv epithelial thiab endothelial cov ntaub so ntswg, feem ntau yog basal ntau dua li nruj junctions.
Dab tsi yog qhov txawv ntawm zonula adherens thiab Desmosomes?
Epithelial hlwb tau tuav ua ke los ntawm kev sib txuas ruaj khov (adherens) junctions. macula adherens (desmosomes) uas muaj nruab nrab filaments. Lub zonula adherens junction nyob hauv qab ntawm tight junction (suav nrog kev sib tshuam). … Cov cadherins los ntawm cov hlwb uas nyob ib sab cuam tshuam rau 'zipper' txog ob lub hlwb ua ke.
hom cell twg muaj adherens junctions?
Epithelial cells tau tuav ua ke los ntawm kev muaj zog anchoring (zonula adherens) junctions. Lub adherens hlws ris nyob hauv qab qhov sib tshuam nruj (suav nrog kev sib tshuam). Hauv qhov sib txawv (li 15-20nm) ntawm ob lub hlwb, muaj cov protein hu ua cadherin - cell membrane glycoprotein.
