|
Ryanodine
|
D012433 |
[A methylpyrrole-carboxylate from RYANIA that disrupts the RYANODINE RECEPTOR CALCIUM RELEASE CHANNEL to modify CALCIUM release from SARCOPLASMIC RETICULUM resulting in alteration of MUSCLE CONTRACTION. It was previously used in INSECTICIDES. It is used experimentally in conjunction with THAPSIGARGIN and other inhibitors of CALCIUM ATPASE uptake of calcium into SARCOPLASMIC RETICULUM.

|
Ryanodine Receptor Calcium Release Channel
|
D019837 |
[A tetrameric calcium release channel in the SARCOPLASMIC RETICULUM membrane of SMOOTH MUSCLE CELLS, acting oppositely to SARCOPLASMIC RETICULUM CALCIUM-TRANSPORTING ATPASES. It is important in skeletal and cardiac excitation-contraction coupling and studied by using RYANODINE. Abnormalities are implicated in CARDIAC ARRHYTHMIAS and MUSCULAR DISEASES.

S Phase
|
D016196 |
[Phase of the CELL CYCLE following G1 and preceding G2 when the entire DNA content of the nucleus is replicated. It is achieved by bidirectional replication at multiple sites along each chromosome.

|
S Phase Cell Cycle Checkpoints
|
D059807 |
[Cell regulatory signaling system that controls progression through S PHASE and stabilizes the replication forks during conditions that could affect the fidelity of DNA REPLICATION, such as DNA DAMAGE or depletion of nucleotide pools.

S-Phase Kinase-Associated Proteins
|
D044786 |
[A family of structurally-related proteins that were originally identified by their ability to complex with cyclin proteins (CYCLINS). They share a common domain that binds specifically to F-BOX MOTIFS. They take part in SKP CULLIN F-BOX PROTEIN LIGASES, where they can bind to a variety of F-BOX PROTEINS.

S100 Calcium Binding Protein A6
|
D000075383 |
[An S100 calcium binding protein that contains two EF HAND MOTIFS and plays a role as a calcium sensor and modulator for many cellular processes such as CELL CYCLE progression; CELL MOTILITY and reorganization of the ACTIN CYTOSKELETON. Its expression is induced by growth factors and it is overexpressed in patients with ACUTE MYELOID LEUKEMIA.
