Gene Information

human ... IST1(9798)

General description

IST1 homolog (UniProt: P53990; also known as hIST1, Putative MAPK-activating protein PM28) is encoded by the IST1 (also known as KIAA0174) gene (Gene ID: 9798) in human. IST1 is an ESCRT-III-like protein that is involved in specific functions of the ESCRT machinery. Is required for efficient abscission during cytokinesis. IST1 is also involved in recruiting VPS4A and/or VPS4B to the midbody of dividing cells. During late anaphase, it is 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. It is shown to regulate early endosomal tubulation together with the ESCRT-III complex by mediating the recruitment of SPAST. Six isoforms of IST1 homolog have been described that are generated by alternative splicing.

Specificity

This rabbit polyclonal antibody detects IST1 homolog in human cells. It targets an epitope within the first 189 amino acids from the N-terminal half.

Immunogen

A recombinant fragment corresponding to the first 189 amino acids from the N-terminal half of human IST1 homolog.
