Loss of function: SKD3 encodes a transmembrane protein that plays a crucial role in the regulation of intracellular calcium homeostasis. Mutations in SKD3 can lead to a loss of its function, resulting in impaired calcium transport and dysregulation of calcium signaling. This disruption of calcium homeostasis can affect multiple cellular processes, including cell growth, proliferation, differentiation, and apoptosis.
Altered protein interactions: Mutations in SKD3 can alter its interactions with other proteins, leading to the formation of abnormal protein complexes or the disruption of existing ones. This can interfere with various cellular pathways and signaling cascades, contributing to the development of MGCA7 disease. For example, mutations in SKD3 have been shown to affect its interaction with the protein kinase A (PKA) pathway, which is involved in regulating cellular responses to various stimuli.
Protein misfolding and aggregation: Some mutations in SKD3 can lead to the misfolding of the protein, causing it to aggregate and accumulate within cells. These protein aggregates can be toxic to cells and impair their normal function, contributing to the symptoms of MGCA7 disease.
Impaired calcium-dependent signaling: SKD3 is involved in regulating calcium-dependent signaling pathways, which play a crucial role in various cellular processes. Mutations in SKD3 can disrupt these signaling pathways, affecting the function of cells and tissues. For example, impaired calcium-dependent signaling can affect the immune system, leading to the development of autoimmune disorders like MGCA7.
It's important to note that the exact mechanisms by which mutations in SKD3 cause MGCA7 disease may vary depending on the specific nature of the mutation and its impact on cellular function. Further research is needed to fully understand the molecular and cellular mechanisms underlying the development of MGCA7 disease in individuals with SKD3 mutations.
