Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

Any process in which a protein is transported to, or maintained in, a specific location.

Any process that modulates the surface configuration of a cell.

The specification and formation of anisotropic intracellular organization or cell growth patterns.

The process in which a cell irreversibly increases in size along one axis through simultaneous polarized growth from opposite ends of a cell, resulting in morphogenesis of the cell.

Any process in which a protein is transported to, or maintained in, apical regions of the cell.

Any process that initiates the inactive process of bipolar cell growth, polarized growth from both ends of a cell.

Any process that modulates the frequency, rate or extent of the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising microtubules and their associated proteins.

A cell septum which forms as part of the division site and functions in the compartmentalization of a cell into two daughter cells at division. A division septum spans a cell and does not allow exchange of organelles or cytoplasm between compartments.

Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle.

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.

A high molecular weight complex characterized in S. pombe containing the cell-end anchoring protein Tea1. This complex is transported to the cell ends by microtubules and is involved in bipolar growth and the maintennce of normal cell polarity.

Structure within the hyphal tip of filamentous fungi that acts as an organizing center for hyphal tip growth; may function to supply vesicles to the elongating tip and/or to organize cytoskeletal microfilaments.

The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

The region at the end of the longest axis of a cylindrical or elongated cell.

The region at the end of the longest axis of a cylindrical or elongated cell.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
