Cell line enhanced (Karpas-707, SCLC-21H, U-2 OS, U-266/70, U-266/84, WM-115)

Homotetramer and heterotetramer with other channel-forming alpha subunits, such as KCNA1, KCNA4, KCNA5, KCNA6 and KCNA7. Channel activity is regulated by interaction with the beta subunits, including KCNAB1 and KCNAB2. Identified in a complex with KCNA1 and KCNAB2 (PubMed:11086297). Identified in a complex with KCNA5 and KCNAB1 (By similarity). Identified in a complex with KCNA4 and FYN (By similarity). Interacts with the beta subunit KCNAB1 (PubMed:19713757). Interacts with PTK2B (By similarity). Interacts (via C-terminus) with CTTN (By similarity). Interacts (via N-terminal cytoplasmic domain) with RHOA (GTP-bound form); this regulates channel activity by reducing location at the cell surface in response to CHRM1 activation (By similarity). Interacts with DRD2 (By similarity). Interacts with SIGMAR1; cocaine consumption leads to increased interaction (By similarity). Interacts with ADAM22 (By similarity). Interacts (via C-terminus) with the PDZ domains of DLG1, DLG2 and DLG4 (By similarity). Interacts with CNTNAP2 (PubMed:10624965).
