Chain A,B,C,D   (PIWL2_HUMAN | Q8TC59)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0003729    mRNA binding    Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    GO:0034584    piRNA binding    Interacting selectively and non-covalently with a piRNA, a Piwi-associated RNA, a 24- to 30-nucleotide RNA derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism.
biological process
    GO:0043046    DNA methylation involved in gamete generation    The covalent transfer of a methyl group to C-5 of cytosine that contributes to the establishment of DNA methylation patterns in the gamete.
    GO:0000966    RNA 5'-end processing    Any process involved in forming the mature 5' end of an RNA molecule.
    GO:0030154    cell differentiation    The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
    GO:0031047    gene silencing by RNA    Any process in which RNA molecules inactivate expression of target genes.
    GO:0030718    germ-line stem cell population maintenance    Any process by which an organism or tissue maintains a population of germ-line stem cells.
    GO:0051321    meiotic cell cycle    Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell via two nuclear divisions.
    GO:0007275    multicellular organism development    The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
    GO:0048477    oogenesis    The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.
    GO:0034587    piRNA metabolic process    The chemical reactions and pathways involving piRNAs, Piwi-associated RNAs, a class of 24- to 30-nucleotide RNA derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism.
    GO:0071442    positive regulation of histone H3-K14 acetylation    Any process that activates or increases the frequency, rate or extent of the addition of an acetyl group to histone H3 at position 14 of the histone.
    GO:2000617    positive regulation of histone H3-K9 acetylation    Any process that activates or increases the frequency, rate or extent of histone H3-K9 acetylation.
    GO:0060903    positive regulation of meiosis I    Any process that increases the rate, frequency, or extent of meiosis I, a cell cycle process comprising the steps by which a cell progresses through the first phase of meiosis, in which cells divide and homologous chromosomes are paired and segregated from each other, producing two daughter cells.
    GO:0045727    positive regulation of translation    Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
    GO:0006417    regulation of translation    Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
    GO:0007283    spermatogenesis    The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.
cellular component
    GO:0043186    P granule    A small cytoplasmic, non-membranous RNA/protein complex aggregates in the primordial germ cells of many higher eukaryotes.
    GO:1990923    PET complex    A protein complex that is composed of at least EXD1, TDRD12 and some PIWI protein. The complex is required for MILI slicing-triggered biogenesis and loading of MIWI2 piRNAs
    GO:0033391    chromatoid body    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).
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0097433    dense body    An electron dense body which may contain granules.
    GO:0010370    perinucleolar chromocenter    A chromocenter adjacent to the nucleolus.
    GO:0071546    pi-body    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.
    GO:0005844    polysome    A multiribosomal structure representing a linear array of ribosomes held together by messenger RNA. They represent the active complexes in cellular protein synthesis and are able to incorporate amino acids into polypeptides both in vivo and in vitro.
