"JSRP1" - Junctional sarcoplasmic reticulum protein 1 in Homo sapiens
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

JSRP1Junctional sarcoplasmic reticulum protein 1; Involved in skeletal muscle excitation/contraction coupling (EC), probably acting as a regulator of the voltage- sensitive calcium channel CACNA1S. EC is a physiological process whereby an electrical signal (depolarization of the plasma membrane) is converted into a chemical signal, a calcium gradient, by the opening of ryanodine receptor calcium release channels. May regulate CACNA1S membrane targeting and activity (331 aa)    
Predicted Functional Partners:
CACNA1S
Voltage-dependent L-type calcium channel subunit alpha-1S; Pore-forming, alpha-1S subunit of the voltage-gated calcium channel that gives rise to L-type calcium currents in skeletal muscle. Calcium channels containing the alpha-1S subunit play an important role in excitation-contraction coupling in skeletal muscle via their interaction with RYR1, which triggers Ca(2+) release from the sarcplasmic reticulum and ultimately results in muscle contraction. Long-lasting (L-type) calcium channels belong to the ’high-voltage activated’ (HVA) group (1873 aa)

RWDD2B
RWD domain containing 2B (319 aa)
           
  0.700
UBN2
Ubinuclein-2; Ubinuclein 2; Belongs to the ubinuclein family (1347 aa)
           
  0.682
SRL
Sarcalumenin; May be involved in the regulation of calcium transport (473 aa)
     
   
  0.627
SYPL2
Synaptophysin-like protein 2; Involved in communication between the T-tubular and junctional sarcoplasmic reticulum (SR) membranes; Synaptophysins (272 aa)
     
   
  0.598
KLRG2
Killer cell lectin like receptor G2; C-type lectin domain containing (409 aa)
           
  0.580
RYR1
Ryanodine receptor 1; Calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering muscle contraction following depolarization of T-tubules. Repeated very high-level exercise increases the open probability of the channel and leads to Ca(2+) leaking into the cytoplasm. Can also mediate the release of Ca(2+) from intracellular stores in neurons, and may thereby promote prolonged Ca(2+) signaling in the brain. Required for normal embryonic development of muscle fibers and skeletal muscle. Required for nor [...] (5038 aa)

LACTB2
Endoribonuclease LACTB2; Endoribonuclease; cleaves preferentially 3’ to purine- pyrimidine dinucleotide motifs in single-stranded RNA. The cleavage product contains a free 3’ -OH group. Has no activity with double-stranded RNA or DNA. Required for normal mitochondrial function and cell viability; Belongs to the metallo-beta-lactamase superfamily. Glyoxalase II family (288 aa)
           
  0.541
ATP2A1
Sarcoplasmic/endoplasmic reticulum calcium ATPase 1; Key regulator of striated muscle performance by acting as the major Ca(2+) ATPase responsible for the reuptake of cytosolic Ca(2+) into the sarcoplasmic reticulum. Catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction; Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIA subfamily (1001 aa)
     
   
  0.540
USP16
Ubiquitin carboxyl-terminal hydrolase 16; Specifically deubiquitinates ’Lys-120’ of histone H2A (H2AK119Ub), a specific tag for epigenetic transcriptional repression, thereby acting as a coactivator. Deubiquitination of histone H2A is a prerequisite for subsequent phosphorylation at ’Ser-11’ of histone H3 (H3S10ph), and is required for chromosome segregation when cells enter into mitosis. In resting B- and T- lymphocytes, phosphorylation by AURKB leads to enhance its activity, thereby maintaining transcription in resting lymphocytes. Regulates Hox gene expression via histone H2A deubiq [...] (823 aa)
