They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. Isoform A is required for cell migration during body enclosure and cell shape changes during body elongation. Required for proper localization of other junctional components, such as hmp-1, hmp-2 and jac-1. Isoform b is involved in axonal guidance in a subset of motor neurons.<ref>PMID:11790304</ref> <ref>PMID:12847081</ref> <ref>PMID:9531567</ref>

== Publication Abstract from PubMed ==
 +
In metazoan adherens junctions, beta-catenin links the cytoplasmic tail of classical cadherins to the F-actin-binding protein alpha-catenin. Phosphorylation of a Ser/Thr-rich region in the cadherin tail dramatically enhances affinity for beta-catenin and promotes cell-cell adhesion in cell culture systems, but its importance has not been demonstrated in vivo. Here, we identify a critical phosphorylated serine in the C. elegans cadherin HMR-1 required for strong binding to the beta-catenin homolog HMP-2. Ablation of this phosphoserine interaction produces developmental defects that resemble full loss-of-function (Hammerhead and Humpback) phenotypes. Most metazoans possess a single gene for beta-catenin, which is also a transcriptional coactivator in Wnt signaling. Nematodes and planaria, however, have a set of paralogous beta-catenins; for example, C. elegans HMP-2 functions only in cell-cell adhesion, whereas SYS-1 mediates transcriptional activation through interactions with POP-1/Tcf. Our structural data define critical sequence differences responsible for the unique ligand specificities of these two proteins.
