Inducible, tunable, and multiplex human gene regulation using CRISPR-Cpf1

A method of increasing expression of a target gene in a cell, the method comprising contacting the cell with, or expressing in the cell:

• (a) a first fusion protein comprising a catalytically inactive Lachnospiraceae bacterium ND2006 Cpf1 (dLbCpf1) fused to more than one first dimerization domains, and (b) a second fusion protein comprising at least one activation domain fused to a second dimerization domain that dimerizes with at least one of the first dimerization domains in the first fusion protein in the presence of a dimerizing agent, wherein the first and second dimerization domains are rapamycin analog A/C heterodimerizer DmrA or DmrC, and at least one crRNA that directs the second fusion protein to a regulatory region of the target gene.
