Rabbit anti-Human IST1 Polyclonal Antibody

Uniprot Id

P53990

Target Species

Human

Target Name

IST1

Target Full Name

IST1 homolog

Target Function

ESCRT-III-like protein involved in specific functions of the ESCRT machinery. Is required for efficient abscission during cytokinesis, but not for HIV-1 budding. The involvement in the MVB pathway is not established. Involved in recruiting VPS4A and/or VPS4B to the midbody of dividing cells. During late anaphase, involved in nuclear envelope reassembly and mitotic spindle disassembly together with the ESCRT-III complex: IST1 acts by mediating the recruitment of SPAST to the nuclear membrane, leading to microtubule severing. Regulates early endosomal tubulation together with the ESCRT-III complex by mediating the recruitment of SPAST.

Target Subcellular Location

Cytoplasmic vesicle. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Midbody. Nucleus envelope.

Target Synonyms

hIST1; Increased sodium tolerance 1; Increased sodium tolerance 1 homolog; IST1 homolog; IST1_HUMAN; KIAA0174; MAPK activating protein PM28; MGC117220; MGC128433; Putative MAPK-activating protein PM28

Target Background

This gene encodes a protein with MIT-interacting motifs that interacts with components of endosomal sorting complexes required for transport (ESCRT). ESCRT functions in vesicle budding, such as that which occurs during membrane abscission in cytokinesis. There is a pseudogene for this gene on chromosome 19. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
