TAP Subfamily: RKD
According to (Chardin et al., 2014), the plant specific RWP-RK TF Family can be divided into the two subfamilies NLP (NIN-like proteins) and RKD (RWP-RK domain proteins). Proteins belonging to the subfamily NLP provide an additional PB1 (Phox and Bem 1) domain at their C-terminus (Chardin et al., 2014; Wu et al., 2020). RWP-RK proteins are involved in response to nitrate availability and in nodule interception (Wu et al., 2020).
