Tracellular N- and C-terminal tails, two ProDom domains I11-L161 (N-PD1131) and V492-V640 (C-PD1131) positioned inside the N-terminal and C-terminal of PiT2 respectively14,15. Corresponding to the protein functions of PiT2, loop regions in PD domain, for example 671, 10741, 51730 amino acid residues are essential for amphotropic murine leukemia virus (A-MuLV) binding16,17, and PD domains also play a vital part in keeping N-Desmethyl-Apalutamide Others transport function18. In IBGC households, 23 missense variants have been identified in SLC20A2, and these missense variants are mainly located in two PD domains of PiT219. The PiT2 also includes a 246-aa (about 38 % amino acids of PiT2) large intracellular loop7 domain involving N-PD1131 and C-PD113120. B tger and Pedersen had reported that the PiT2 with deleted loop7 had typical retroviral recognition, and transport functions15. So far, there is certainly no definite evidence that missense variants in loop7 influence the transport function of PiT2 which outcome in IBGC19. For that reason, it remains an intriguing query regarding the function of loop7 domain in the nervous program.Key Laboratory of Molecular Biophysics in the Ministry of Education, Center for Human Genome Research, College of Life Science and Technologies, Huazhong University of Science and Technologies (HUST), Wuhan, 430074, China. 2 College of Life Sciences, Hubei Collaborative Innovation Center for Green Transformation of Bio-Resources, Hubei University, Wuhan, 430062, China. 3Department of Neurology, Xiangya Hospital, Central South University, Changsha, Hunan, 410008, China. 4College of Life Sciences, Northeast Standard University, Changchun, 130024, China.

To reveal the function of loop7 in PiT2, we performed yeast two-hybrid screening and identified microtubule-associated protein 1B (MAP1B) as a novel interactor of loop7 in PiT2. MAP1B i.
