Recombinant Human Intraflagellar transport protein 81 homolog (IFT81)

Uniprot Id

Q8WYA0

Target Species

Human

Target Name

IFT81

Target Full Name

Intraflagellar transport protein 81 homolog

Target Function

Component of the intraflagellar transport (IFT) complex B: together with IFT74, forms a tubulin-binding module that specifically mediates transport of tubulin within the cilium. Binds tubulin via its CH (calponin-homology)-like region. Required for ciliogenesis. Required for proper regulation of SHH signaling.

Target Subcellular Location

Cell projection, cilium.

Target Protein Families

IFT81 family

Target Tissue Specificity

Highly expressed in testis, moderately in ovary, heart, liver, skeletal muscle, kidney and pancreas, low in prostate, brain, placenta and lung and not detected in spleen, thymus, small intestine and colon. Isoform CDV-1R is abundantly expressed in testis.

Target Synonyms

Carnitine deficiency associated expressed in ventricle 1 isoform 2; Carnitine deficiency-associated protein expressed in ventricle 1; CDV-1; CDV1 ; CDV1R ; Ift81; IFT81_HUMAN; intraflagellar transport 81 homolog (Chlamydomonas); Intraflagellar transport protein 81 homolog

Target Background

The protein encoded by this gene, together with IFT74, forms a tubulin-binding module of intraflagellar transport complex B. This module is involved in transport of tubulin within the cilium, and the encoded protein is required for ciliogenesis. Mutations in this gene are a cause of short-rib polydactyly syndromes.
