A CARPID‐derived protein interactome study of MALAT1 (W. Yi et al., 2020) identified guanine nucleotide‐binding protein G(S) protein, involved in cell proliferation and migration (X. Jin, Zhu, et al., 2019); Ras‐like proto‐oncogene A (RAS‐A); and minichromosome maintenance complex component 4 (MCM4) of the family of cancer‐contributing proteins (Y. Wang, Chen, et al., 2020). Here, MCM4 is linked to cancer.
