Functioni

Together with BCAR1 it may play a role in the control of epithelial cell polarity. Involved in the organization of apical junctions in kidney cells, together with NPHP4 and RPGRIP1L/NPHP8. Does not seem to be strictly required for ciliogenesis. Seems to help to recruit PTK2B/PYK2 to cell matrix adhesions, thereby initiating phosphorylation of PTK2B/PYK2 and PTK2B/PYK2-dependent signaling. May play a role in the regulation of intraflagellar transport (IFT) during cilia assembly. Required for normal retina development. In connecting photoreceptor cilia influences the movement of some IFT proteins such as IFT88 and WDR19. Involved in spermatogenesis; required for the differentiation of early elongating spermatids into spermatozoa.3 Publications

Pathology & Biotechi

Disruption phenotypei

Mice are viable without renal manifestations of nephronophthisis. Male mice are infertile with oligoteratozoospermia. Spermatogenesis is blocked at the early stages of spermatid elongation, with degenerating spermatids sloughing off into the lumen. Early elongating spermatids are detached from Sertoli cells and show a failure of sperm head and tail morphogenesis and an abnormal F-actin distribution. Severe retinal degradation with mislocalized rhodopsin, disorganized outer segments, restricted expression of transducin to the inner segment and abnormal intraflagellar transport (IFT) of IFT57.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
