NECAB1 (N-terminal EF-hand calcium-binding protein 1) is a calcium-binding protein belonging to the EF-hand superfamily, characterized by its conserved helix-loop-helix structural motifs that enable calcium ion coordination. Primarily expressed in neuronal tissues, NECAB1 is enriched in the brain, particularly in regions like the hippocampus, cortex, and striatum, suggesting roles in calcium-mediated signaling pathways critical for synaptic plasticity, neurotransmitter release, and neuronal development. It interacts with proteins involved in vesicle trafficking, such as synaptobrevin/VAMP2. and modulates presynaptic functions by regulating calcium dynamics. NECAB1 also associates with membrane receptors, including dopamine receptors, and influences downstream signaling cascades. Beyond neuroscience, it has been implicated in cancer, where dysregulated expression correlates with tumor progression and metastasis. Recombinant human NECAB1 protein is widely employed in biochemical studies to explore its calcium-dependent conformational changes, interaction networks, and potential as a therapeutic target. Its conserved structure across vertebrates underscores its functional importance, yet detailed mechanisms linking its calcium-sensing ability to cellular outcomes remain an active research area. This protein’s dual role in physiological and pathological contexts makes it a compelling subject for interdisciplinary studies spanning neurobiology, oncology, and molecular pharmacology.
