This activates survival pathways, such as NF-kB, reduces cell death, and promotes cell growth. 2) when TRPC1 joins TRPC4 channel (1 TRPC1 and TRPC4) it pushes away Ca²⁺ as TRPC1 has an aminio acid(K639) which is positively charged pushing the positively charged calcium. It also develops more preference for Na⁺/K⁺ over Ca²⁺, while increasing inhibitor sensitivity. 3. TRPC4 is essential during early postnatal brain development, as it helps dendrites grow and stay stable by turning glutamate signals into calcium entry, activating a force-generating pathway. Without TRPC4, dendrites will disintegrate.
