Protein kinase C and casein kinase substrate in neurons protein 1 is an enzyme that in humans is encoded by the PACSIN1 gene.[5][6]
This is nonsense.
Please see the scientific literature on Syndapin I in the PubMED database of scientific literature.
PACSIN1 has been shown to interact with GTPases of the Dynamin family (Dynamin 1, 2 and 3). Based on this interaction, its localization and functional role the protein was named syndapin I (synaptic dynamin-associated protein I) - a scientific more useful and more widely used name than PACSIN1.
Subsequently, a variety of further interactions have been published (see PubMED database and search for syndapin I).
