The protein encoded by this gene is a component of junctional complexes and is composed of a C-terminal hydrophobic segment spanning the endoplasmic/sarcoplasmic reticulum membrane and a remaining cytoplasmic domain that shows specific affinity for the plasma membrane. CAG/CTG repeat expansion from normally 6-28 repeats to 40-59 repeats in the 3' UTR of this gene have been associated with Huntington disease-like 2 (HDL2). This gene is a member of the junctophilin gene family. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Jul 2016]. * **<color #00a2e8>UniProt Summary</color>**: Junctophilins contribute to the formation of junctional membrane complexes (JMCs) which link the plasma membrane with the endoplasmic or sarcoplasmic reticulum in excitable cells. Provides a structural foundation for functional cross-talk between the cell surface and intracellular calcium release channels. JPH3 is brain- specific and appears to have an active role in certain neurons involved in motor coordination and memory. <button type='primary' size='sm' modal='Pfam_Domains'>Pfam Domains</button> <button type='primary' size='sm' modal='GO_terms'>GO Terms</button> <modal id='Pfam_Domains' size='lg' title='Pfam Domains'> |MORN| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |junctional membrane complex| |junctional sarcoplasmic reticulum membrane| |calcium-release channel activity| |exploration behavior| |regulation of ryanodine-sensitive calcium-release channel activity| |neuromuscular process controlling balance| |regulation of neuronal synaptic plasticity| |release of sequestered calcium ion into cytosol| |negative regulation of sequestering of calcium ion| |calcium ion transmembrane import into cytosol| |calcium ion transport into cytosol| |regulation of release of sequestered calcium ion into cytosol| |regulation of calcium ion transmembrane transporter activity| |cytosolic calcium ion transport| |regulation of calcium-mediated signaling| |regulation of calcium ion transport into cytosol| |neuromuscular process| |memory| |regulation of sequestering of calcium ion| |learning| |regulation of calcium ion transmembrane transport| |regulation of cation channel activity| |regulation of synaptic plasticity| |calcium ion transmembrane transport| |regulation of calcium ion transport| |calcium ion transport| |regulation of ion transmembrane transporter activity| |learning or memory| |regulation of transmembrane transporter activity| |regulation of transporter activity| |positive regulation of cytosolic calcium ion concentration| |divalent metal ion transport| |cognition| |divalent inorganic cation transport| |regulation of cytosolic calcium ion concentration| |regulation of cation transmembrane transport| |regulation of metal ion transport| |cellular calcium ion homeostasis| |modulation of chemical synaptic transmission| |regulation of trans-synaptic signaling| |calcium ion homeostasis| |cellular divalent inorganic cation homeostasis| |regulation of ion transmembrane transport| |divalent inorganic cation homeostasis| |cellular metal ion homeostasis| |inorganic cation transmembrane transport| |regulation of transmembrane transport| |behavior| |cation transmembrane transport| |metal ion homeostasis| |cellular cation homeostasis| |metal ion transport| |cellular ion homeostasis| |inorganic ion transmembrane transport| |regulation of ion transport| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |molecular function| |ion homeostasis| |cation transport| |cellular homeostasis| |regulation of cellular localization| |endoplasmic reticulum membrane| |ion transmembrane transport| |endoplasmic reticulum| |chemical homeostasis| |transmembrane transport| |locomotion| |ion transport| |nervous system process| |homeostatic process| |regulation of intracellular signal transduction| |establishment of localization in cell| |regulation of transport| |system process| </modal> \\ === CRISPR Data === <button type='primary' size='small' modal='Compound_Hit'>Compound Hit</button> <button type='default' size='small' modal='Most_Correlated_Genes'>Most Correlated Genes in Chemogenomics</button> <button type='primary' size='small' modal='Essential_Avana'>Tissues where Essential in the Avana Dataset (DepMap 20Q1)</button> <modal id='Compound_Hit' size='lg' title='Compound Hit'> ^Screen^Score^ |[[:results:exp112|S-DABN 8μM R03 exp112]]|2.04| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> No correlation found to any other genes in chemogenomics. </modal> <modal id='Essential_Avana' size='lg' title='Tissues where Essential in the Avana Dataset (DepMap 20Q1)'> Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| </modal> == Essentiality in NALM6 == * **<color #00a2e8>Essentiality Rank</color>**: 6819 * **<color #00a2e8>Expression level (log2 read counts)</color>**: 0.11 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='JPH3 Expression in NALM6 Cells: 0.11'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2026/01/07 22:36by 127.0.0.1
