The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.

The directed movement of substances from the Golgi to the plasma membrane in transport vesicles that move from the trans-Golgi network to the plasma membrane, where they fuse and release their contents by exocytosis.

Fusion of the membrane of a transport vesicle with its target membrane.

The process in which cells that are products of meiosis acquire the specialized features of ascospores. Ascospores are generally found in clusters of four or eight spores within a single mother cell, the ascus, and are characteristic of the ascomycete fungi (phylum Ascomycota).

During ascospore formation, the process in which each haploid nucleus becomes encapsulated by a double membrane.

During ascospore formation, the process in which each haploid nucleus becomes encapsulated by a double membrane.

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a prospore membrane.

The prospore membrane is a double-membraned structure that extends from the cytoplasmic face of the spindle pole bodies to encompass the spindle pole bodies and the four nuclear lobes that are formed during meiosis. It helps isolate the meiotic nuclei from the cytoplasm during spore formation and serves as a foundation for the formation of the spore walls. An example of this component is found in Schizosaccharomyces pombe.
