establishment and/or maintenance of neuroblast cell polarity

The specification, formation and maintenance of the apicobasal polarity of a neuroblast cell, a progenitor of the central nervous system.

establishment and/or maintenance of epithelial cell polarity

The specification, formation and maintenance of the apicobasal polarity of an epithelial cell.

establishment of epithelial cell polarity

The specification and formation of the apicobasal polarity of an epithelial cell.

The maintenance of the apicobasal polarity of an epithelial cell.

Catalysis of the cleavage of the Arg-Xaa bond in Lys-Arg-Xaa and Arg-Arg-Xaa to process Yeast alpha-factor pheromone and killer toxin precursors.

Catalysis of the hydrolysis of proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. Hydrolyzes peptide amides.

Catalysis of the preferential cleavage of Arg-Xaa bonds in small molecule substrates. Highly selective action to release kallidin (lysyl-bradykinin) from kininogen involves hydrolysis of Met-Xaa or Leu-Xaa. The rat enzyme is unusual in liberating bradykinin directly from autologous kininogens by cleavage at two Arg-Xaa bonds.

Catalysis of the release of an N-terminal tripeptide from a polypeptide.

Catalysis of the preferential cleavage of Arg-Xaa, Lys-Xaa.

Catalysis of the hydrolysis of peptide linkages in oligopeptides or polypeptides by a reaction mechanism in which threonine residues act as nucleophiles.

A myosin complex containing a class I myosin heavy chain and associated light chains; myosin I heavy chains are single-headed, possess tails of various lengths, and do not self-associate into bipolar filaments; myosin I complexes are involved in diverse processes related to membrane traffic and cell movement.

The process by which voltage-gated sodium and potassium ion channels become localized to distinct subcellular domains in the neuron. Specific targeting, clustering, and maintenance of these channels in their respective domains are essential to achieve high conduction velocities of action potential propagation.
