Summary: Enables actin filament binding activity and identical protein binding activity. Involved in negative regulation of protein localization to nucleus. Acts upstream of or within several processes, including apical junction assembly; negative regulation of neuroblast proliferation; and regulation of signal transduction. Located in several cellular components, including intercalated disc; lamellipodium; and zonula adherens. Part of flotillin complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Used to study patterned macular dystrophy 2.

alpha-Catenin acetylation is essential for its stability and blocks its tumor suppressor effects in breast cancer through Yap1.
Title: α-Catenin acetylation is essential for its stability and blocks its tumor suppressor effects in breast cancer through Yap1.
beta-catenin has an TCF/LEF-independent nuclear function that coordinates an extensive network of myogenic genes in cooperation with MyoD; and an alpha-catenin-dependent membrane function that helps control cell-cell interactions
Title: β-Catenin is essential for differentiation of primary myoblasts via cooperation with MyoD and α-catenin.
alpha-catenin represents a bona fide tumor suppressor for the development of lobular-type breast cancer and as such provides an alternative event to E-cadherin inactivation, adherens junction dysfunction, and subsequent constitutive actomyosin contraction.
Title: αE-catenin is a candidate tumor suppressor for the development of E-cadherin-expressing lobular-type breast cancer.
alphaE-catenin knockout caused heart failure, the upregulation of hypertrophic genes, and the dysregulation of fatty acid metabolism via the transcriptional activity of Yap and beta-catenin.
Title: Cardiospecific deletion of αE-catenin leads to heart failure and lethality in mice.
alphaE-catenin is essential for inhibiting nuclear YAP localization and cell proliferation. This function of alphaE-catenin is required for formation of the tooth signalling centre, the enamel knot (EK), which maintains dental mesenchymal condensation and epithelial invagination. alphaE-catenin restricts YAP/TAZ activity to establish a group of non-dividing and specialized cells that constitute a signalling centre.
Title: αE-catenin inhibits YAP/TAZ activity to regulate signalling centre formation during tooth development.
Catna1 functions as a positive regulator of pancreatic islet cell lineage differentiation by repressing the sonic hedgehog pathway.
Title: αE-Catenin Is a Positive Regulator of Pancreatic Islet Cell Lineage Differentiation.
alpha-catenins regulate intercalated disc maturation and actomyosin contractility, which, in turn, control Yap subcellular localization, thus providing an explanation for the loss of proliferative capacity in the newborn mammalian heart.
Title: α-Catenin-dependent cytoskeletal tension controls Yap activity in the heart.
In this study, the authors revealed how alpha-catenin retains its activated state while avoiding unfolding under tension.
Title: Mechano-adaptive sensory mechanism of α-catenin under tension.
cadherin 2 (CDH2) and CDH4 cooperate to regulate radial migration in mouse brain via the protein tyrosine phosphatase 1B (PTP1B) and alpha- and beta-catenins.
Title: Cadherin 2/4 signaling via PTP1B and catenins is crucial for nucleokinesis during radial neuronal migration in the neocortex.
alphaT-catenin is a constitutively active actin-binding protein that can physically couple the cadherin.catenin complex to F-actin in the absence of tension.
Title: αT-Catenin Is a Constitutive Actin-binding α-Catenin That Directly Couples the Cadherin·Catenin Complex to Actin Filaments.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
