Functional Descriptions
The maize transfer cell-specific type-A response regulator ZmTCRR-1 appears to be involved in intercellular signalling.
ZmTCRR-1, that codes for a member of the type-A response regulator class of proteins.
The ZmTCRR-1 protein was detected not only in the transfer-cell layer, but also in the conductive tissue deep inside the endosperm, where there is no transcription of the gene.
The promoter of ZmTCRR-1 is activated by the transfer cell-specific transcriptional activator ZmMRP-1.
