OR13D1 Gene

HGNC Family G protein-coupled receptors
Name olfactory receptor, family 13, subfamily D, member 1
Description Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. [provided by RefSeq, Jul 2008]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nThe leucine‐rich repeat (LRR)–containing proteins described in these studies appear to be multifunctional regulators in both pluripotent and reproductive cell contexts. In murine pluripotent stem cells, one protein—LRRC34—is highly expressed and displays dynamic regulation upon differentiation. Its activity is linked not only to the maintenance of pluripotency, through modulation of key factors such as Oct4, but also to nucleolar functions including ribosome biogenesis by interacting with nucleolar proteins like Nucleophosmin and Nucleolin. Moreover, LRRC34 has been implicated in telomere length regulation, as its downregulation in embryonic stem cells reduces telomerase activity and telomere elongation while affecting the expression of other telomere-associated genes."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its role in pluripotency, LRRC34 is relevant to spermatogonial stem cell (SSC) biology. Studies show that LRRC34 is expressed in defined subpopulations of undifferentiated spermatogonia, and its transient knockdown in SSCs leads to reduced colony sizes accompanied by significant changes in transcriptome profiles and apoptotic pathways. These observations suggest a critical role for LRRC34 in SSC proliferation and overall transcriptomic regulation."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "3"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nA separate study focuses on another member of the LRR protein family, Spata34, which is predominantly expressed in testicular germ cells. Initially identified as a testis-specific gene with robust expression in round and elongating spermatids and proposed to act as a transcriptional repressor in the p53/p21 pathway, further research using a gene knockout mouse model indicated that Spata34 is not essential for male fertility despite its specific expression pattern.
