DDR1

A gene on chromosome 6p21.3 that encodes a receptor tyrosine kinase belonging to the subfamily homologous to Dictyostelium discoideum protein discoidin (Discoidin Domain-containing Receptor); it is expressed only in epithelial cells (kidney, lung, GI tract, brain) and involved in cell–cell interactions and recognition.

Molecular pathology
DDR1 is overexpressed in various tumours.

Ability to function with less external memory -- The SH77721 SoC device can perform its processing using only one DDR2 (Double Data Rate 2) SDRAM chip (a DDR333 type), instead of the four external DDR1 (Double Data Rate 1) memory chips required by the SH7770 SH-Navi device, thus enabling obvious reductions in system costs.
