Protein–protein interactions networks of PMCA2-interacting partners. Interaction networks of 474 unique proteins associated with PMCA2 were computed by STRING software to predict the likelihood being the PMCA2-interacting partners based on confidence level. a High confidence (score ≥ 0.70). b Medium confidence (0.40 < score < 0.70). c Low confidence (0.15 < score ≤ 0.40). PMCA2 encoded by ATP2B2 gene is highlighted in a red-dotted circle. Only protein nodes that displayed direct interactions to PMCA2 are reported as potential PMCA2-interacting proteins in Table 1 (parts IIa–IIc)
