Introduction of MFSD5
Tejada-Jiménez reported a molybdate transporter different from the molybdate transporter type 1 (MOT1) family, which is encoded by the Chlamydomonas reinhardtii gene MOT2 (CrMoT2) and is also present in animals including humans (HsMOT2 ). HsMOT2 gene is mapped to the chromosome 12 position 12q13.3 and has been named as major facilitator superfamily domain-containing protein 5 (MFSD5). MFSD5 knockdown leads to a lack of uptake activity of molybdate. MFSD5 is composed of 450 amino acids and shows the typical hydrophobicity pattern of a membrane protein. With 12 transmembrane regions, MFSD5 transcripts are detected in many tissues and cell types, with higher transcript accumulation in the cervix, stomach, nerves, and skin.

Function of MFSD5 Membrane Protein
Almost all living organisms need to get molybdenum (Mo) from the external environment to achieve the basic physiological processes of life. In these processes, some important enzymes (such as sulfite oxidase, aldehyde oxidase, etc.) are required, and they play important roles strictly depending on the presence of Mo. The cells absorb Mo in the form of molybdate oxide, which requires a molybdenum transporter. MOT1 is the first molybdate transporter identified in plant eukaryotes, but it does not exist in the animal genome. MFSD5 transcription is activated under conditions of low Mo availability and is partially inhibited by the presence of ammonium as a nitrogen source; in contrast to MoT1, the presence of nitrate has no effect on the expression of MFSD5. Although MOT1 is related to nitrate assimilation requirements, MFSD5 may help to ensure that molybdate is provided in the scarcity of the anion. Since animals do not absorb nitrate, the molybdate transporters in these organisms are not related to nitrate metabolism.

Application of MFSD5 Membrane Protein in Literature
This study indicates that LjMOT1 may be involved in the transport of Mo, which lays a theoretical foundation for further understanding of the Mo transport mechanism of higher plants.
This article reports a molybdate transporter different from the MOT1 family, encoded by the Chlamydomonas reinhardtii gene MoT2, which opens the way for understanding molybdate transport as part of dynamic molybdenum homeostasis and molybdenum biosynthesis.
This paper investigates the effects of molybdenum deficiency and molybdate transporter mutation (MOT1) on nitrogen and sulfur metabolism in Arabidopsis and is the first survey of the effects of Mo nutrition and MOT1 on plant gene expression and metabolism.
This paper demonstrates that the natural variation in Mo content in Arabidopsis germplasm branches is controlled by the variation of the molybdenum transporter 1-MOT1, which belongs to the sulfate transporter superfamily, providing insights into the regulation of Mo accumulation in plants.
This article shows that the sulfate transporter SHST1 increases the uptake of molybdate into cells at the nM concentration, but molybdate reduces the sulfate transport of SHST1.
