O00499

功能描述

是控制质膜曲率、膜塑形和膜重塑的关键因子。在肌肉细胞中,T-tubules(横小管)的形成所必需的,T-tubules是质膜的管状内陷,在去极化-收缩偶联中发挥作用 (PubMed:24755653)。是内吞作用的负调节因子 (By similarity)。还参与细胞内囊泡分选的调节、BACE1运输的调节以及淀粉样蛋白β产生的控制 (PubMed:27179792)。在神经回路中,内吞调节可能影响PHF-tau聚集体的内化 (By similarity)。可能参与MYC活性的调节和细胞增殖的控制 (PubMed:8782822)。具有肌动蛋白成束活性,并在体外稳定肌动蛋白丝以抵抗解聚 (PubMed:28893863)。 {ECO:0000250|UniProtKB:O08839, ECO:0000269|PubMed:24755653, ECO:0000269|PubMed:27179792, ECO:0000269|PubMed:28893863, ECO:0000269|PubMed:8782822}。

组织特异性

Ubiquitous. Highest expression in the brain and muscle (PubMed:9182667). Expressed in oligodendrocytes (PubMed:27488240). Isoform IIA is expressed only in the brain, where it is detected in the gray matter, but not in the white matter (PubMed:27488240). Isoform BIN1 is widely expressed with highest expression in skeletal muscle.
