InterPro domain: IPR033243

This entry includes a group of plant zinc finger proteins, including JACKDAW from Arabidopsis. They bind DNA via their zinc fingers [ 1 ].

JACKDAW (JKD) protein is a transcription factor that regulates tissue boundaries and asymmetric cell division by a rapid up-regulation of 'SCARECROW' (SCR), thus controlling the nuclear localization of 'SHORT-ROOT' (SHR) and restricting its action [ 2 ]. It controls epidermal patterning in the Arabidopsis root meristem [ 3 ]. It directly regulates SCR and MAGPIE (MGP) expression in cooperation with SHR, SCR and MGP [ 4 ].
