The change in form (cell shape and size) that occurs during sexual reproduction in order to facilitate direct contact between the compatible mating types in organisms that undergo conjugation cellular fusion.

The targeting of proteins to a membrane that occurs after their translation. Some secretory proteins exhibit posttranslational transport into the endoplasmic reticulum (ER) lumen: they are synthesized in their entirety on free cytosolic ribosomes and then released into the cytosol, where they are bound by chaperones which keep them in an unfolded state, and subsequently are translocated across the ER membrane.

The process that results in incorporation of a protein into an endoplasmic reticulum (ER) membrane. It depends on specific topogenic sequences of amino acids that ensure that a protein acquires the proper orientation during its insertion into the ER membrane.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

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

A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.

An ER membrane insertion complex that contains subunits that recognize two types of transmembrane domain signals. In budding yeast the complex contains Get4p, Get5p, Sgt2p, and at least two heat shock proteins (HSPs).
