PACSIN1

PACSIN1 has biased expression in brain (RPKM 42.1) and lymph node (RPKM 1.5).

Protein Kinase C And Casein Kinase Substrate In Neurons 1

Plays a role in the reorganization of the microtubule cytoskeleton via its interaction with MAPT; this decreases microtubule stability and inhibits MAPT-induced microtubule polymerization. Plays a role in cellular transport processes by recruiting DNM1, DNM2 and DNM3 to membranes. Plays a role in the reorganization of the actin cytoskeleton and in neuron morphogenesis via its interaction with COBL and WASL, and by recruiting COBL to the cell cortex. Plays a role in the regulation of neurite formation, neurite branching and the regulation of neurite length. Required for normal synaptic vesicle endocytosis; this process retrieves previously released neurotransmitters to accommodate multiple cycles of neurotransmission. Required for normal excitatory and inhibitory synaptic transmission (By similarity).
Binds to membranes via its F-BAR domain and mediates membrane tubulation.

Colocalizes with MAPT in axons. In primary neuronal cultures, present at a high level in presynaptic nerve terminals and in the cell body. Colocalizes with DNM1 at vesicular structures in the cell body and neurites (By similarity).
Associates with membranes via its F-BAR domain.

Phosphorylated by casein kinase 2 (CK2) and protein kinase C (PKC).
