CACNG1 Gene

HGNC Family Ion channels
Name calcium channel, voltage-dependent, gamma subunit 1
Description Voltage-dependent calcium channels are composed of five subunits. The protein encoded by this gene represents one of these subunits, gamma, and is one of two known gamma subunit proteins. This particular gamma subunit is part of skeletal muscle 1,4-dihydropyridine-sensitive calcium channels and is an integral membrane protein that plays a role in excitation-contraction coupling. This gene is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members that function as transmembrane AMPA receptor regulatory proteins (TARPs).

Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n CACNG1 encodes the γ‐subunit of L‐type voltage‐dependent Ca²⁺ channels and was originally identified in skeletal muscle, where it plays a key role in modulating channel gating and calcium influx. This regulation is essential for proper excitation–contraction coupling and the maintenance of calcium homeostasis. Several studies have shown that changes in CACNG1 expression are associated with muscle remodeling processes: for example, increased expression has been linked to atrophic responses in myotubes under conditions such as microgravity exposure or denervation, suggesting that CACNG1 may help adjust calcium signaling during muscle atrophy and repair processes."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": " In addition, differential expression of CACNG1 has been observed in clinical contexts such as metastatic breast cancer, where its down‐regulation in early progressors compared to long responders implies that its expression level might relate to cellular signaling events that affect tumor cell behavior."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "3"}]}, {"type": "t", "text": " Moreover, as one of several members of the Ca²⁺ channel γ subunit family, CACNG1 contributes to the fine-tuning of channel function through its physical association with the core pore-forming subunit, thereby influencing not only muscle physiology but also potentially other cell types where calcium-dependent signaling is critical."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "4"}]}, {"type": "t", "text": "\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Risa Okada, Shin-Ichiro Fujita, Riku Suzuki, et al.
