| GO:0007286 | spermatid development | biological_process | The process whose specific outcome is the progression of a spermatid over time, from its formation to the mature structure. [GOC:dph, GOC:go_curators] |
| GO:0030719 | P granule organization | biological_process | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of polar granules, cytoplasmic, non-membranous RNA/protein complex aggregates in the primordial germ cells of many higher eukaryotes. [PMID:10851135, PMID:770367] |
| GO:0141007 | siRNA-mediated retrotransposon silencing by heterochromatin formation | biological_process | A retrotransposon silencing mechanism in which a siRNA triggers heterochromatin assembly. Heterochromatin is a chromatin conformation that is refractory to transcription. [PMID:36570931] |
| GO:0033391 | chromatoid body | cellular_component | A ribonucleoprotein complex found in the cytoplasm of male germ cells, composed of exceedingly thin filaments that are consolidated into a compact mass or into dense strands of varying thickness that branch to form an irregular network. Contains mRNAs, miRNAs, and protein components involved in miRNA processing (such as Argonaute proteins and the endonuclease Dicer) and in RNA decay (such as the decapping enzyme DCP1a and GW182). [PMID:17183363] |
| GO:0045202 | synapse | cellular_component | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110] |
| GO:0071546 | pi-body | cellular_component | A P granule that contains the PIWIL2-TDRD1 module, a set of proteins that act in the primary piRNA pathway. The pi-body corresponds to the cementing material between mitochondria found in gonocytes. [GOC:sp, PMID:20011505] |
| GO:0034587 | piRNA processing | biological_process | A process leading to the generation of a functional piRNA. piRNAs (Piwi-associated RNAs) are a class of 24- to 30-nucleotide RNAs derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism. [GOC:kmv, PMID:23329111, PMID:24696457, PMID:34724117] |
| GO:0007283 | spermatogenesis | biological_process | The developmental process by which male germ line stem cells self renew or give rise to successive cell types resulting in the development of a spermatozoa. [GOC:jid, ISBN:9780878933846, PMID:28073824, PMID:30990821] |
| GO:0043186 | P granule | cellular_component | A small cytoplasmic, non-membranous RNA/protein complex aggregate in the primordial germ cells of many higher eukaryotes. [GOC:dph, GOC:kmv, PMID:11262230] |
