Characterisation of a new splice variant of MASK-BP3(ARF) and MASK human genes, and their expression patterns during haematopoietic cell differentiation.

In this study we report the characterisation of a new splice variant, here denominated splice variant 4 (accession number AF258557) of the human Multiple Ankyrin repeats Single KH domain (hMASK) (accession number AF521882) and the hMASK-4E-Binding Protein 3 Alternative Reading Frame (hMASK-BP3(ARF)) (accession number AF521883), containing a number of ANK-repeat motifs. Ankyrin (ANK) repeat-containing proteins carry out a wide variety of biological activities and are involved in processes, such as cell differentiation and transcriptional regulation. The present study reports the computer analysis of these splice variant cDNAs and their broad mRNA expression in different normal human tissues and cancer cell lines. An upregulation of the splice variant mRNAs expression was observed after HL-60 and erythroblast differentiation. The upregulation of splice variant 4 mRNA was considerably higher than those of the other variants, during erythroid differentiation.

Effects of different hypothetical detection mechanisms on the shape of spatial-frequency filters inferred from masking experiments: I. Noise masks.

The detectability of a sinusoidal grating was measured in a standard two-interval forced-choice experiment against backgrounds of noise gratings of the same orientation as the signal. The noise gratings were either spatially high-pass or low-pass filtered and were either unchanged in each observation interval (static) or flickering at a rate that depended on their cutoff frequency (dynamic). Spatial-frequency-selective mechanisms are inferred from the data and their characteristics shown to depend on assumptions concerning the detection process thought to follow the spatial-frequency-selective device.
