Gene name, corresponding UniProt ID, and protein name are indicated for each candidate. TM, Single or multiple predicted transmembrane domains, based on UniProt (04/2020). Only candidate protein partners with MS/MS ratio KCC2/sham >2 in at least two of the three replicates are shown, ranked first by the number of replicates in which they were identified and then by the descending mean MS-MS count in the three replicates.

*Candidates identified in the previous KCC2 interactome (Mahadevan et al., 2017).
