A transcriptional repressor complex that contains the lin-9, lin-35, lin-37, lin-52, lin-53, lin-5is involved in 4-, dpl-1 and efl-1 proteins, and is involved in cell fate specification.
A polymeric IgA immunoglobulin complex that is complexed with one chain of secretory component (SC). Polymeric IgA is present in mucosal areas, having been transported via a transcytosis mechanism in mucosal epithelial cells relying on the polymeric Ig receptor, a portion of which then remains bound to the polymeric IgA as secretory component.
The process of transporting polymeric IgA and polymeric IgM immunoglobulin, via transcytosis mediated by the polymeric immunoglobulin receptor (pIgR), from the basolateral surface to apical surface of an epithelial cell. At the apical surface the immunoglobulin binding portion of the pIgRis cleaved and remains bound to the transported immunoglobulin as secretory component (SC). The same process is used for the transport and excretion of IgA immune complexes to the luminal surface of the mucosa.
Binding to a LIM domain (for Lin-11 Isl-1 Mec-3) of a protein, a domain with seven conserved cysteine residues and a histidine, that binds two zinc ions and acts as an interface for protein-protein interactions.
